WMZT Miniature Circuit Breakers
Overview
Eaton WMZT miniature circuit breakers
offer optimum and efficient protection
for branch and control circuits up to 40
amps. The WMZT series is available with
C or D trip characteristics in accordance
with UL489. These circuit breakers are
current limiting, which means they interrupt fault currents within one half cycle
of the fault. The WMZT series is DIN-rail
mountable and can be used in branch
circuit applications.
Listings
• UL Listed and Recognized under UL 489
Category DIVQ File E7819
Category DKSY2 File E7819
Category DIHS E64983
• CSA 22.2, No. 5 File 245545
• CE LVD 2006/95/EC
• IEC/EN 60947-2
Features and Benefits
• Complete range of UL489 listed DIN rail
mounted miniature circuit breakers up
to 40 ampere current rating
• Single pole, two-pole and three pole
models
• Current limiting design provides fast
short circuit interruption that reduces
the
let-through energy, which can damage
the circuit
• Suitable for branch circuit device
protection
• Thermal-magnetic overcurrent protection
— two levels of short circuit protection,
categorized by C and D curves
C curve magnetic trip point:
5 to 10 times the rated current,
typically used for small
transformers, pilot devices, etc.
D curve magnetic trip point:
10 to 20 times the rated current,
typically used for transformers or loads
with very high inductive loads.
• Trip-free design — breaker cannot be
defeated by holding the handle in the
“ON” position
• Captive screws cannot be lost
• SWD (switching duty) rated circuit
breaker — suitable for switching
fluorescent
lighting loads (In m 20A)
• Fulfills UL 489, CSA C22.2 No.5 and also
IEC 60947-2 Standard
• Can also be used in applications for
which UL 1077 or CSA C22.2 No.235 are
also allowed
• Field installable shunt trip and auxiliary
switch subsequent mounting (See Allowable Combinations page)
• Module width of only 17.7 mm (per pole)
• Contact position indicator (red / green)
• 35mm DIN-rail mountable, utilizing
spring clip
• Suitable for reverse feed applications
Applications
Feeder and Branch Circuit Protection
• Convenience receptacle circuits
(internal / external)
• Motor control circuits
• Load circuits leaving the equipment
(external)
• HACR Equipment (Heating Air Conditioning, Refrigeration)
• PLC I/O points
• Computers
• Power supplies
• Control instrumentation
• Relays
• UPS
• Power conditioners

Eaton WMZT miniature circuit breakers are available with “C”
and “D” tripping characteristics.
The front of each Eaton WMZT miniature circuit breaker is
labeled for positive identification.

Type C trip curve: 5 to10 In
ZIPLink
Connection
System
C-curve devices are suitable for applications where medium
levels of inrush current are expected. Applications include small
transformers, lighting, pilot devices, control circuits and coils.
C-curve devices provide a medium magnetic trip point.
Multi-wire
Connectors
Sensor Cables
and Connectors
Type D trip curve: 10 to 20 In
D-curve devices are suitable for applications where high levels
of inrush current are expected. The high magnetic trip point
prevents nuisance tripping in high inductive applications such
as motors, transformers and power supplies.

Blocks
Eaton WMZT devices are current limiting, which means they
interrupt fault currents within one half cycle of the fault. Current limiting devices offer superior protection by reducing peak
let-through current and energy.
