QO290 - 90 Amp Circuit Breaker

QO290 - 90 Amp Circuit Breaker

If you need a 90 amp, 2-pole circuit breaker for a compatible QO load center, the Square D QO290 is built for the job. It provides overcurrent and short-circuit protection for 120/240VAC electrical systems while offering the convenience of a plug-on installation. With a 10kA interrupting rating, it's suited for protecting larger branch circuits in residential, commercial, and light industrial applications.

The plug-on design makes installation quick in compatible QO panels, which can save time during panel upgrades or routine breaker replacement. Once installed, the breaker monitors the circuit continuously and trips when electrical current exceeds safe operating levels, helping reduce the risk of damage to wiring and connected equipment. For electricians, maintenance teams, and property owners, it's a practical replacement option when a 90-amp, 2-pole QO breaker is required.
