Tripping Mechanisms
A tripping mechanism is an assembly within the circuit breaker molded case that causes the circuit
breaker to open automatically under sustained overload or short circuit conditions.
The tripping mechanisms in two- and three-pole circuit breakers operate such that an overcurrent on
any pole of the circuit breaker will cause all poles of the circuit breaker to open simultaneously.
Thermal and magnetic factory calibration (with current) is performed on each pole of every Square D
circuit breaker.
These mechanisms operate to trip the circuit breaker:
Thermal trip
Magnetic trip
Optional shunt trip accessory (see Accessories, page 12)
The sensing system is an integral part of a thermal-magnetic circuit breaker. The sensing system
continually monitors current flowing through the circuit breaker. It detects abnormal current conditions
and, depending on the magnitude of the current, initiates an inverse-time or an instantaneous tripping
response. This action causes the tripping mechanism to open the circuit breaker contacts and interrupt
current flow. The speed of the tripping process must be controllable and inversely matched to the
severity of the overcurrent. QOU miniature circuit breakers have an over-center toggle mechanism for
quick-make, quick-break action with positive handle indication. The handle assumes a position
between ON (I) and OFF (O) when the circuit breaker has tripped.
