UL 1077 DIN rail supplementary protectors
FAZ circuit breakers
PRODUCT OVERVIEW
Six tripping curves to choose from
Trip-free design;
breaker cannot be
defeated by holding
the handle in the
ON position
Color-coded indicator
provides breaker
status for easy
troubleshooting
Breaker information
printed on the front
of the device for
quick identification
Even though not required by NEC or CEC for supplementary
protectors, Eaton’s FAZ devices are current limiting, which
means that they interrupt fault currents within one half cycle.
Current limiting devices offer superior protection by reducing
peak let-through current and energy.

Eaton FAZ supplementary protectors are available with six
different tripping characteristics, including Type B, C, D, K, S, and Z.
Definitions for each trip curve are contained on the ordering pages
and can be used to determine the optimal characteristic for your
application. For example, low-level short-circuit faults in control
wiring, such as PLCs, are best protected by devices with Type B
trip characteristics (3–5X continuous rating of the device (In).

PRODUCT OVERVIEW
Applying branch circuit breakers and supplementary
protectors in North America
Characteristics of IEC-style miniature circuit breakers
Because FAZ miniature circuit breakers are IEC-style devices,
it is important to understand their inherent characteristics before
examining them in the context of UL/CSA requirements.
The Eaton series offer two types of miniature circuit breakers
for use in North America. The first version, FAZ-NA(RT), fully
complies with the molded-case circuit breaker standard UL 489
and the Canadian equivalent CSA 22.2 No. 5-09, which states that
devices within that range can be applied legitimately as feeder
and branch circuit protective devices per the U.S. and Canadian
electrical codes.
A second version, FAZ, is recognized per UL 1077 and certified
per CSA C22.2 No. 235 as a supplementary protector and can
be fully used per the NEC and CEC Codes in that capacity.
For international purposes, the entire FAZ family is CE marked
and in full conformity with the applicable IEC standards for
miniature circuit breakers, EN/IEC 60898 and EN/IEC 60947-2.
•
IEC-style miniature circuit breakers are thermal-magnetic,
inverse time protective devices, with both a fixed thermal
and a fixed magnetic trip setting
•
They are toggle operated, and like all modern circuit
breakers, feature a “trip-free” mechanism; this means
that the tripping action works independently of the handle
position for safety purposes
•
They all mount on a standard 35 mm DIN rail and share
a common single pole width of 17.5 mm
•
Most comply with EN/IEC 60898 and EN/IEC 60947-2,
which are the relevant international performance and testing
standards for low voltage (<1000V) circuit breakers in Europe
and the rest of the IEC world
•
Outside North America, they can be used in both residential
and industrial applications as feeder and branch circuit
protective devices
•
In North America, most European miniature circuit breakers
are only UL recognized and CSA certified as “supplementary
protectors,” meaning that they cannot be utilized as feeder
or branch circuit protective devices per the local electrical
codes. This commonly restricts their use to applications where
“closer” protection is desired than that offered by a branch
circuit protection device
•
Some variations, like the FAZ-NA(RT) line have been specially
designed to meet UL and CSA requirements for molded-case
circuit breakers and are marked accordingly. This makes them
suitable for feeder and branch circuit protection applications
in North America
Both FAZ and FAZ-NA(RT) are offered in various ampere ranges
and tripping characteristics. This paper will focus on the main
technical aspects of the entire line and should assist in the
proper selection and application of all versions.

PRODUCT OVERVIEW
Supplementary protectors
As mentioned, the standard FAZ line fulfills all of the criteria
per code of “supplementary overcurrent protective devices,”
or “supplementary protectors,” as they are better known.
What is the definition of a supplementary protector
per North American standards?
Typically, the branch circuit overcurrent protective device
(BOPD) will be either a listed molded-case circuit breaker
or a fuse. Supplementary protectors, such as FAZ devices
from the Eaton series, can therefore be added to any of
these branch circuits to “supplement” the branch circuit
protection. Examples of applications ideally suited for these
devices can include:
A supplementary protector is a manual reset device designed
to open the circuit automatically on a predetermined value
of time versus current or voltage within an appliance or other
electrical equipment. It may also be provided with manual
means for opening or closing the circuit. (Source: UL 1077)
•
Any type of OEM electrical equipment that is fed from
a service panel board and that often requires additional
protection for sensitive internal circuitry and components
(test and medical equipment, copiers and printers, computers
and power supplies, etc.)
In the United States (and similarly in Canada) the NEC 2005
further defines supplementary protectors as devices intended
to provide limited overcurrent protection for specific applications,
such as lighting fixtures and appliances. This limited protection
is in addition to the protection provided in the required branch
circuit by the branch circuit overcurrent protective device.
•
The need for manual reset devices with optional accessories
such as auxiliary contacts and voltage trips to accomplish
fuseless protective circuit designs and enhance operational
diagnostics
•
Isolation and protection of control cable, coils, contacts, and
circuit elements of motor control circuits tapped from the load
side of the branch circuit protective device (per NEC 430.72)
•
Protection of control circuit transformers, especially in the
secondary where the manual reset protector can be used
to isolate, as well as protect, secondary circuit conductors
and loads
Clearly, the underlying message in those definitions is that
supplementary protectors are not branch circuit overcurrent
protective devices per code, and neither are they tested that
way per UL and CSA standards. They cannot replace the primary
protective role performed by listed and certified molded case
circuit breakers and fuses.
That explains, in part, their status by UL as “recognized only”
devices. Supplementary protectors will never bear a UL listing
mark, simply because their suitability as protective devices is
dependent on a number of acceptability conditions that can
vary from make to make and ultimately define the manner in
which they can be properly applied per code. The manufacturer
should be consulted in all cases when evaluating the suitability
of “recognized only” components such as UL 1077
supplementary protectors.
FAZ protectors are not subject to any specific restrictions in this
respect, other than, like all supplementary protectors, they must
never be used as a substitute for true listed and certified primary
overcurrent protective devices.
Where can supplementary protectors be used effectively
per code standards?
Eaton series FAZ supplementary protectors can be used
in a number of significant areas. To more clearly illustrate
potential applications, however, let’s first present the NEC’s
definition of a branch circuit:
IEC-based miniature circuit breakers, such as the entire FAZ line,
are much more than just conventional supplementary protectors
from an internal design point of view and can provide an ideal
means to enhance the protective capabilities of any circuit.
•
As mentioned, they are in full compliance with the pertinent
EN/IEC standards (EN/IEC 60898, EN/IEC 60947-2) for miniature
circuit breakers and can thus be applied, outside of North
America, as full-fledged stand-alone overcurrent protective
devices in both residential and industrial applications
•
As this typical let-through current curve shows, they are highly
current limiting devices that appreciably limit the amount of
let-through current and destructive energy within their ratings
to minimize damage levels to downstream loads and circuits
Circuit breakers that are classified as “current limiting” have
the ability to clear damaging short-circuit currents within the
first half-cycle of the fault, resulting in better overall protection
for all circuit components.
•
They come in a variety of tripping characteristics, which
is ideal when customizing protection to match specific load
requirements. FAZ supplementary protectors offer a total
of six different protection characteristics for this purpose:
B, C, D, K, S, and Z tripping characteristics
•
They feature a number of electrical accessories to enhance
the performance and diagnostic capabilities of control panels,
as well as a means to facilitate panel mounting and wiring
The circuit conductors between the final overcurrent device
protecting the circuit and the outlets. (Source: NEC)
A branch circuit is that portion of the electrical distribution
system that extends beyond the final branch circuit overcurrent protective device and is intended to serve lighting,
appliance, motors, and/or other individual loads.

Tripping characteristics
Miniature circuit breakers are thermal-magnetic, inverse-time
tripping devices. From a thermal point of view, all FAZ protectors
are calibrated to trip at the same level, which is 135% of the
device’s fixed current rating for single-pole and 145% for
multi-pole at an ambient reference temperature of 40°C.
NNote: Higher ambient temperatures, as well as density of mounting
groups, can all be accommodated but may be subject to de-rating
factors. Please consult technical data for further information and
appropriate curves.
It is the response time of the magnetic trip that differentiates
each characteristic and for which an identifying letter is assigned.
The IEC 898 standard only specifically covers the B, C, and D
characteristics. The rest can vary from brand to brand, but
essentially follow a uniform convention.

As previously mentioned, we have expanded our FAZ line
of miniature circuit breakers to include a version that is listed
and certified as a molded-case circuit breaker (UL 489 and
CSA No. 5).
This line is rated up to 40A and comes in single-, two-, and
three-pole versions with instantaneous trip characteristics B,
C and D. Of course, the line is also in conformity with the
IEC standard for molded-case circuit breakers, IEC 60947-2,
and can therefore be universally applied.
The NEC defines a circuit breaker as follows:
A device designed to open and close a circuit by nonautomatic means and to open the circuit automatically
on a predetermined overcurrent without damage to itself
when properly applied within its rating.
Note the text in italics. In the eyes of the code, that definition
sets circuit breakers apart from any other protective device and
establishes their role as primary overcurrent protective switches
in all types of electrical circuits. UL listing (and CSA Certification)
requires additionally that regular testing on circuit breakers be
conducted by UL and CSA at the manufacturer’s plant to monitor
construction and verify their performance.

As already mentioned, all Eaton series FAZ devices are
current-limiting by design. In the case of the UL 489 devices,
they are also classified by UL/CSA in that manner and are
marked on the label.
A circuit breaker that is marked as a current-limiting device
is one that does not use a fusible element and, when operating
within its current-limiting range, limits the let-through energy
(I2t) to less than the energy of a half-cycle wave of the available
symmetrical current.

Short-circuit markings on FAZ devices
Below is a tabulated summary of short-circuit rating values that
apply to the FAZ line of supplementary protectors and moldedcase circuit breakers.
It is important to keep in mind that short-circuit markings
on FAZ supplementary protectors (UL 1077) and FAZ-NA(RT)
molded-case circuit breakers (UL 489) must not be interpreted
in the same manner.
Supplementary protectors have short-circuit markings in
association with upstream primary overcurrent protective
devices. Conversely, molded-case circuit breakers are primary
overcurrent protective devices, and their ratings thus refer
to their short-circuit interrupting capability.
