| 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 |
| 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 |
