Miniature Curcuit Breakers

MINIATURE CIRCUIT BREAKERS

Square D QO®, QOB (Bolt-On), QOU (Unit Mount) and HOM miniature circuit breakers provide a wide range of options to meet various requirements.

  • QO miniature circuit breakers can be plug-on or bolt-on for installation in load center and panelboard interiors or mounting bases.
  • QOU miniature circuit breakers have lugs at both ends and can be DIN rail-, flush- or surface-mounted.
  • Both QO and QOU have a factory-preset thermal and magnetic trip element in each pole. Multi-pole circuit breakers have a single handle with a common internal trip that indicates whether the circuit breaker is OFF, ON or TRIPPED with a red Visi-Trip® indicator that becomes visible when the breaker has tripped and interrupted the circuit.
  • Both QO and QOU meet UL 1699 and NEC 210.12 standards and allow reverse connections without restrictive line/load marking.
  • HOM breakers are slightly larger than QO and also offer CAFI, Dual Function options and more.
