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 2 and 3-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
