ED42B025 - 25Amp Circuit Breaker

ED42B025 - 25Amp Circuit Breaker

Looking for a dependable replacement breaker that fits your existing Siemens electrical system? The Siemens ED42B025 is a 25 Amp, 2-pole molded case circuit breaker designed to provide reliable circuit protection in commercial and industrial applications while maintaining compatibility with Siemens ED-frame equipment. Built as a form, fit, and functional replacement, this breaker helps simplify maintenance by allowing you to replace an existing compatible device without modifying your panel or distribution equipment.

The ED42B025 features a thermal magnetic trip unit that delivers two levels of protection. The thermal element responds to sustained overload conditions, while the magnetic element reacts quickly to short circuits, helping protect conductors and connected equipment from electrical faults.
