BRH120 - 20 Amp Circuit Breaker

BRH120 - 20 Amp Circuit Breaker

The Eaton BRH120 is a 20 Amp single-pole thermal magnetic circuit breaker designed for use in compatible Eaton Type BR loadcenters. It provides protection against overloads and short circuits in 120/240V electrical systems and is commonly used on receptacle circuits, lighting circuits, and other general-purpose branch circuits in residential, commercial, and light industrial applications.

The breaker installs using a plug-on mounting design and accepts #14–4 AWG copper or aluminum conductors.

Whether you're replacing an existing breaker or maintaining a compatible Eaton BR loadcenter, the BRH120 provides a straightforward solution for branch-circuit protection in applications requiring a 20 Amp, single-pole breaker with a 22 kAIC rating.
