ED42B030 - 30Amp Circuit Breaker

ED42B030 - 30Amp Circuit Breaker

The Siemens ED42B030 is a 30 Amp, 2-pole molded case circuit breaker designed to provide dependable circuit protection for commercial and industrial electrical distribution systems. Built specifically for use with Siemens ED-frame equipment, this breaker serves as a form, fit, and functional replacement for compatible installations, making it easy to maintain existing electrical systems without modifying the panel. Whether you're replacing an aging breaker during scheduled maintenance or restoring an existing installation, the ED42B030 offers the electrical ratings and physical compatibility needed for a straightforward replacement.

At the heart of the ED42B030 is a thermal magnetic trip unit that delivers two levels of protection. The thermal element responds to sustained overload conditions, while the magnetic trip reacts quickly to short circuits, helping protect conductors and connected equipment from damaging fault conditions.
