For providing overload and short circuit protection
QO and QOB circuit breakers have an overcenter, trip-free toggle mechanism with quick-make, quickbreak action and positive handle indication
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
Plug-on QO circuit breakers are for use in QO load centers, NQ and NQOD panelboards, OEM mounting bases, and Speed D™ switchboard distribution panels
QO and QOB circuit breakers have VISI-TRIP feature, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit
