ED42B030L - 30Amp Circuit Breaker

ED42B030L - 30Amp Circuit Breaker

Need a dependable way to keep your electrical system protected and operating efficiently? The Siemens ED42B030L is a 30 Amp, 2-pole molded case circuit breaker designed to provide reliable circuit protection in commercial and industrial electrical distribution systems. Built for seamless compatibility with Siemens ED-frame equipment, this breaker serves as a form, fit, and functional replacement for compatible installations without requiring panel modifications. Whether you're performing scheduled maintenance or replacing an existing breaker in a legacy system, the ED42B030L offers the electrical ratings and physical compatibility needed to help keep your equipment operating safely and efficiently.

The thermal magnetic trip unit combines two essential levels of protection in a single device. The thermal element responds to sustained overload conditions, while the magnetic trip reacts quickly to short-circuit faults, helping protect conductors and connected equipment from damage.
