E42B025 - 25Amp Circuit Breaker Description
E42B025 - 25Amp Circuit Breaker
When maintaining an existing electrical system, finding the right circuit breaker is about more than matching amperage. The E42B025 molded case circuit breaker is designed to provide the proper fit, function, and protection characteristics required for compatible electrical distribution equipment. Rated at 25 amps with a 2-pole configuration, this breaker helps protect circuits from overloads and short circuits while supporting the continued operation of commercial and industrial power systems.
With an interrupting rating of 25kA at 240VAC and 18kA at 480VAC, the E42B025 is suitable for applications where maintaining original electrical specifications is important. Its HACR rating also makes it appropriate for many heating, air conditioning, and refrigeration systems that require this designation. Whether you're replacing a failed breaker during maintenance, servicing facility equipment, or keeping an existing distribution system operational, this breaker delivers the ratings and compatibility needed to help get the job done.
Designed for operation in environments up to 40°C (104°F), the E42B025 includes both line-side and load-side terminals, helping simplify installation in compatible assemblies. Its molded case construction is built to last and intended for long-term use in demanding commercial and industrial environments where dependable circuit protection remains essential.
