BR220ST - 20 Amp Circuit Breaker

BR220ST - 20 Amp Circuit Breaker

The Eaton BR220ST is a 20 Amp, two-pole thermal magnetic circuit breaker designed for use in compatible Eaton Type BR loadcenters. Featuring an integrated shunt trip mechanism, this breaker allows remote tripping from an external control signal, making it a practical choice for applications where circuits must be disconnected quickly as part of an emergency shutdown system, safety interlock, fire alarm interface, or other remote-control operation. Rated for 120/240V AC systems, the BR220ST combines dependable overload and short-circuit protection with the added functionality of remote tripping, helping electrical systems meet operational and safety requirements in a wide range of residential, commercial, and light industrial installations.

Whether you're installing it to protect HVAC equipment, pumps, compressors, electric heating systems, machinery, or dedicated 240-volt circuits, the Eaton BR220ST delivers the combination of circuit protection and remote trip functionality that electricians, contractors, facility managers, and maintenance personnel frequently require. Its compatibility with existing Type BR systems also makes it a popular option for panel upgrades, equipment replacements, and facility maintenance projects.
