E42B025 - 25Amp Circuit Breaker Description
E42B025 - 25 Amp Circuit Breaker
The E42B025 molded case circuit breaker is designed for dependable circuit protection in electrical distribution systems that require a 2-pole, 25-amp bolt-on breaker within an E42 frame. Built to provide consistent overcurrent protection, this breaker helps safeguard wiring, equipment, and connected loads from damage caused by overloads or short circuits. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, the E42B025 supports a range of commercial and industrial electrical panels where reliable circuit interruption is required. Its bolt-on mounting design offers a secure connection to the panelboard bus, while included load-side terminals help simplify installation. Rated for 40°C environments and HACR applications, this molded case circuit breaker is well suited for maintaining the original form, fit, and function in compatible legacy electrical systems. These breakers were built to last and continue to serve as dependable replacements when maintaining existing infrastructure.
