QO Series Main Breaker

The Square D QOM60VH is a 60 A two-pole miniature circuit breaker rated for 120/240 VAC systems. It provides thermal-magnetic overcurrent protection and switching for residential and light-commercial panels. The unit carries UL listing under file E84967 and CSA certification under master contract 153555. Its VisiTrip indicator shows at a glance when the breaker has opened the circuit.

Bolt-On Panel Integration

This breaker uses a bolt-on mounting method that secures directly to the panel bus, freeing a DIN-rail slot for other devices. Two poles occupy adjacent positions and deliver 22 kA interrupting capacity on both AC and DC networks. Quick-make, quick-break toggle action and a trip-free mechanism ensure reliable isolation during maintenance or fault conditions. Factory accessory provisions allow shunt trips, auxiliary switches or alarm switches to be added later.

Sustained Fault Performance

Thermal-magnetic operation responds to prolonged overloads as well as short-circuit peaks without nuisance tripping. The 22 kA breaking capacity is maintained across the full 120/240 V range during extended fault events. Positive handle indication remains accurate after repeated operations, and the transparent cover lets inspectors verify contact status without removing the breaker. Trip-free design prevents the handle from being held closed against a persistent fault.

Questions about this item

At what current will the 22 kA breaking capacity limit be reached during a sustained fault?

The breaker interrupts faults up to 22 kA at 120/240 VAC; sustained overloads above 60 A cause thermal tripping before the magnetic limit is tested.

How much heat does the 60 A two-pole unit dissipate when running continuously at full load?

Continuous 60 A operation produces typical thermal-magnetic breaker warmth; the VisiTrip indicator remains clear unless an overload trips the mechanism.

Which panel bus or mounting hardware must I already have to install this bolt-on QO main breaker?

A Square D QO load centre with matching bolt-on bus stab spacing is required; the breaker mounts directly onto that bus without extra brackets.
