In 1955 Square D Company introduced the QO® Plug-on System and
revolutionized the way electrical contractors install miniature circuit breakers
in the United States. Today, as part of Schneider Electric, we offer the same
Plug-on System technology around the world. A full line of IEC Certified QO
products are available for residential, commercial and industrial
applications.

International Miniature Circuit Breakers
CHARACTERISTICS
Advantages of the Plug-on System
0739DB9901R11/03
June 2004
•
Circuit breakers are rated 240 Vac single-phase and 415 Vac threephase, 50/60 Hz, 3–100 A.
•
•
Circuit breakers are available in 1-, 2- or 3-pole construction.
•
RCBO devices available with 10 mA, 30 mA and 100 mA residual
current protection.
•
Trip-free handle ensures tripping even when the circuit breaker is held or
locked in the ON position.
•
Circuit breakers are in compliance with international standards set by
the International Electrotechnical Commission (IEC).
•
The CE marking is located on each circuit breaker in accordance with
the low-voltage directive of the European Union.
•
The entire QO circuit breaker family provides the advantage of a plug-on
connection. (Bolt-on connections also available.)
•
A 50% reduction on installation time compared to a lug/lug (DIN)
alternative.
•
•
•
No link bars to fit and tighten.
Thermal trip elements are factory calibrated to 40°C (IEC 947-2) and
30°C (IEC 898) ambient temperature.
Contact jaws automatically align the circuit breakers in the equipment.
High short circuits result in an increase in jaw pressure reducing the
potential for hazardous arcs on the line side of the circuit breaker.

Figure 25:
International Miniature Circuit Breakers
QOE-RCBO branch circuit breakers with residual current protection and
integral overcurrent protection are designed for use in single-phase
consumer unit and three-phase distribution panelboard applications.
•
Compliance with International Standards: Certified to IEC 60898 and
BS4293, 10 kA at 240 Vac, 50/60 Hz, CE marked.
•
ON/OFF Indication: ON/OFF markings are on the face of the circuit
breaker along with the international I/O markings.
•
Handle Operation: Trip-free handle through an over-center toggle
mechanism that ensures tripping even when the handle is held or locked
in the ON position.
•
Trip Indication: Indication of a tripped circuit breaker on overload or
short circuit is by location of the handle in the OFF position. Indication of
a tripped circuit breaker on residual current ground fault is by location of
the handle in an intermediate position.
•
Push-to-test Function: A yellow push-to-test button is positioned on
the front of the device for testing the residual current electronic trip
circuit and mechanical tripping interface.
•
Thermal Trip Element: Thermal trip elements are factory calibrated at
30°C ambient temperature.
•
Instantaneous trip level types B and C:
— Type B—(3–5 In) Overcurrent protection for sensitive equipment
— Type C—(5–10 In) Overcurrent protection for all application types

•
Residual Current Protection: Residual ground-fault trip currents are
factory set at 10 mA, 30 mA or 100 mA: Type A.
•
Trip Mechanism: Device will trip on loss of neutral. Device is sensitive
to both ac and pulsating dc fault current. Device will trip on voltage
between neutral and earth greater than 50 Vac.
•
Mounting: Plug-on connection.

Push-to-test Function: A yellow push-to-test button is positioned on the
front of the device for testing the residual current electronic trip circuit
and mechanical tripping interface.
Thermal Trip Element: Thermal trip elements are factory calibrated at
40°C ambient temperature.
•
Residual Current Protection: Residual ground-fault trip currents are
factory set at 10 or 30 mA.
•
Endurance (Switching Operation):
— 1,500 full-load operations
— 8,500 no-load operations

Handle Padlock Attachments (QO1PA and QOHPL)
The handle padlock attachment allows padlocking the circuit breaker
handles in the ON or OFF position. They are available in two styles:
fixed and removable. The fixed style is intended to be a permanent
device. The padlock can be removed to resume normal operation. The
removable style is intended to be a temporary device and must be
removed to resume normal operation. Padlock is not included.
Handle Tie (QO1HT)
The handle tie accessory converts any adjacent 1-pole QO circuit
breaker to one independent-trip, multi-pole circuit breaker.
The handle clamp accessories fasten the handle in the ON or OFF
position. These handle clamps cannot be padlocked.

QOXD CIRCUIT BREAKERS
QOXD Circuit Breaker
•
Compliance with International Standards: Certified to IEC
947-2 (3 kA [10–63 A]) and IEC 898 (3 kA [10–32 A]) at 240 Vac single
phase and 415 Vac three phase, 50/60 Hz, CE marked.
•
ON/OFF Indication: ON/OFF markings are on the face of the circuit
breaker along with the international I/O markings.
•
Handle Operation: Trip-free handle through an over-center toggle
mechanism that ensures tripping even when the handle is held or locked
in the ON position.
•
Trip Indication: Indication of a tripped circuit breaker on overload or
short circuit is by location of the handle in the center position. The circuit
breaker is also equipped with the Square D exclusive Visi-Trip® indicator
(a luminescent, red trip indicator on the front of the circuit breaker).
•
Thermal Trip Element: Thermal trip elements are factory calibrated at
40°C ambient (IEC 947-2) and 30°C ambient (IEC 898) temperature.
•
Endurance (Switching Operations):
07393010
Figure 41:
QOXD branch circuit breakers are designed for use in single-phase
consumer unit and three-phase distribution panelboard applications.
— IEC 947-2: 1,500 full-load operations
— IEC 947-2: 8,500 no-load operations
