Eaton BR220ST Industrial Molded Case Circuit Breaker

Description:

The Eaton BR220ST Type BR circuit breaker is used in industrial and commercial electrical distribution systems to provide overcurrent and short-circuit protection for 120/240V branch circuits. It includes an integrated shunt trip function for remote or automated tripping in safety, emergency shutdown, or control system applications. Commonly installed in load centers, control panels, and OEM equipment where reliable circuit protection and remote disconnect capability are required. Maintenance teams and electrical contractors use this breaker for system protection upgrades, panel replacements, and safety circuit integration.

Applications:

The Eaton BR220ST circuit breaker is commonly used in industrial control panels, HVAC systems, machinery power distribution, emergency shutdown circuits, and commercial electrical load centers where 2-pole 120/240V protection with remote trip capability is required. It is typically installed in manufacturing facilities, building infrastructure systems, and OEM equipment requiring both standard protection and shunt-trip controlled disconnect functionality.
