Square D Miniature Circuit Breakers

Square D by Schneider Electric has created four different lines of miniature circuit breakers for residential and industrial circuit protection. They are: lighting panelboard miniature circuit breakers, Homeline miniature circuit breakers, QO and QOB miniature circuit breakers and QOU unit mount circuit breakers.

A special feature provided by most of Square D miniature circuit breakers is the VISI-TRIP indication. When the circuit breaker has tripped, the handle moves to the center position and the red VISI-TRIP indicator appears in a window in the circuit breaker case. Trip indication immediately provides a visual indication that the circuit breaker has been tripped and interrupted the circuit.

Lighting panelboard miniature circuit breakers are designed to be used with the NF series lighting panelboards. NF lighting panelboards are used for commercial and industrial lighting and electrical distribution. Lighting panelboard miniature circuit breakers have current ratings from 15 to 125 Amps.

Homeline miniature circuit breakers are designed for fast installation and superior circuit protection. They have a full range of amperages, poles and advanced function devices that offer Arc Fault, Combination Arc Fault (CAFI), Ground Fault (Class A, GFCI) and Dual Function (CAFI and GFCI) protection.

QO and QOB miniature circuit breakers come in a complete range of amperages and interrupting ranges to fit into various QO distribution panels. Plug-on QO circuit breakers are used in NQ panelboards, QO load centers or Speed-D switchboard distribution panels. Bolt-on QOB are used in NQOD panelboards. 

QOU unit mount circuit breakers are used for overcurrent protection and switching on both AC and DC electrical systems. They are available for flush, surface or DIN rail mounted applications in one, two or three pole constructions.
