STANDARD BOLT-ON
QO® and QOB circuit breakers have an overcenter, trip-free toggle mechanism with quick-make, quickbreak action and positive handle indication
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
Bolt-on QOB circuit breakers are for use in NQO and NQOD panelboards
QO® and QOB circuit breakers have Visi-Trip® feature, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit
Common trip
10 kA at 240 VAC, 5 kA at 48 VDC interrupt rating
