Standard thermal-magnetic QO® and Homeline™ 15 and 20 A circuit breakers are listed to UL489 and provide overload and short circuit protection for conductors. The QO® and Homeline™ thermal-magnetic circuit breakers are for general use in protecting branch circuit in residential and commercial applications. Use QO® and Homeline™ 15 and 20 A arc fault circuit interrupter circuit breakers that have been listed to UL1699 in order to provide arc fault circuit protection for the entire branch circuit in accordance with the installation requirements in National Electrical Code section 210.12. Thermal-magnetic circuit breakers are not designed, listed or intended to provide protection against low level hazardous arcing conditions in branch circuit wiring.

  • QO™ and QOB circuit breakers have an over center, trip-free toggle mechanism with quick-make, quick break 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
  • 8 to 2 AWG aluminum/copper wire
