Features

  • 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 panel boards
  • 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 120/240 VAC, 5 kA at 48 VDC interrupt rating
  • 8 to 2 AWG aluminum/copper wire
  • Standard
