BR250ST - 50 Amp Circuit Breaker

BR250ST - 50 Amp Circuit Breaker

The Eaton BR250ST is a 50 Amp, two-pole circuit breaker designed for use in compatible Eaton Type BR loadcenters. In addition to standard thermal-magnetic circuit protection, this model includes a factory-installed shunt trip that allows the breaker to be opened remotely through an external control signal.

The common-trip design opens both poles at the same time if a fault occurs, while the shunt trip function provides a way to disconnect power from a remote location when required by the application. This type of breaker is often used in systems tied to emergency stop controls, fire alarm interfaces, building automation equipment, machinery controls, security systems, and other installations where remote tripping is part of the design.

You'll find the BR250ST in commercial buildings, industrial facilities, schools, healthcare environments, apartment complexes, mechanical rooms, and equipment control systems. In many cases, the reason for selecting this breaker is straightforward: the panel requires a Type BR breaker, the circuit requires a 50 Amp two-pole device, and the application calls for remote tripping capability.

Like many Eaton BR breakers that remain in service for years, the BR250ST is designed for continued operation when installed and used within its intended ratings.

Where It Works Best

• The BR250ST is commonly used in Eaton Type BR panels installed in commercial buildings, industrial facilities, schools, healthcare facilities, apartment complexes, and equipment control systems. Typical applications include emergency shutdown circuits, fire alarm interface systems, building automation equipment, motor controls, pumps, compressors, HVAC equipment, machinery disconnect circuits, and other installations requiring a 50 Amp two-pole breaker with remote tripping capability. It is also frequently used during panel maintenance and replacement projects where maintaining compatibility with existing Eaton Type BR equipment is important.
