E43B025 - 25Amp Circuit Breaker

E43B025 - 25 Amp Circuit Breaker

The E43B025 molded case circuit breaker is designed for use in electrical distribution systems that require a dependable 25-amp, 3-pole protective device within an E43 frame configuration. Built to provide proper circuit protection against overloads and short circuits, this breaker supports installations operating at up to 480VAC with an 18kA interrupting rating and 25kA at 240VAC. Its bolt-on mounting style helps ensure a secure mechanical and electrical connection inside compatible panelboards and switchboards. Rated for 40°C operation and HACR applications, the E43B025 is suitable for heating, air-conditioning, and refrigeration circuits where these ratings are required. The breaker includes load-side terminals, simplifying installation and helping maintain proper conductor connections. Designed for durability and consistent operation, this molded case circuit breaker provides the correct form, fit, and function replacement for equipment originally designed to use E43 frame breakers.
