Square D QOM70VH Main Breaker
The Square D QOM70VH is a 70 A two-pole miniature circuit breaker from the QO series rated for 120/240 VAC service. It uses a thermal-magnetic trip mechanism with a trip-free toggle and provides a 22 kA interrupting rating. The bolt-on design fits compatible load centres and includes VisiTrip indication for quick fault identification. Box lug connectors accept one 4 AWG to 2/0 copper or aluminium conductor.
For panel builders replacing a main breaker
Electricians and panel builders who need a 70 A main breaker with bolt-on mounting and 22 kA breaking capacity will find this device matches the spec. The unit is UL Listed under file E84967 and CSA Certified under master contract 153555. Installers requiring a plug-on style, a different ampere rating, or a higher interrupting rating should select an alternative breaker.
70 A 2-pole rating at 120/240 VAC
The decisive specification is the 70 A two-pole rating at 120/240 VAC combined with a 22 kA interrupting capacity. This value determines whether the breaker can safely protect the intended service entrance conductors and coordinate with the available fault current. Verify the load centre accepts QO bolt-on mains before ordering.

Questions about this item
Will the 70 A two-pole breaker fit in my existing Square D QO load center?
Yes, it is a standard QO series bolt-on main breaker designed for QO panels and measures 5.09 in high by 3.47 in wide by 5.00 in deep.
How can I confirm the breaker is protecting the circuit after installation?
The VisiTrip indicator shows a visible red flag when the breaker has tripped, and the positive handle indication displays the exact on, off or tripped position.
What wire sizes do the box lug connectors accept and is anything else needed to mount it?
The lugs accept one 4 AWG to 2/0 copper or aluminum conductor per pole; the breaker bolts directly onto the panel bus so no separate mounting hardware is required.
