BR245 - 45 Amp Circuit Breaker

BR245 - 45 Amp Circuit Breaker

The Eaton BR245 is a two-pole, 45 Amp circuit breaker designed for use in compatible Eaton Type BR loadcenters. Rated for 120/240V AC applications, it is commonly used on dedicated circuits serving air conditioning systems, heat pumps, electric water heaters, compressors, pumps, electric heating equipment, and other loads that require a 45 Amp two-pole breaker.

A thermal-magnetic trip unit provides protection against overloads and short circuits. If a fault occurs, the common-trip design opens both poles at the same time. The plug-on mounting style allows the BR245 to install directly into approved Eaton BR panels without changing the existing panel layout.

You'll find the BR245 in homes, apartments, workshops, garages, office buildings, retail spaces, and light commercial facilities. Typical applications include HVAC equipment, electric heating systems, water heaters, pumps, compressors, and other dedicated 240-volt circuits.

Like many Eaton BR breakers that remain in service for years, the BR245 is designed for continued operation when installed and used within its intended ratings.
