ED43B100 - 100Amp Circuit Breaker

ED43B100 - 100Amp Circuit Breaker

If you're replacing a breaker in a compatible Siemens ED frame panel, the Siemens ED43B100 is designed to make that job straightforward. Instead of searching for a different style or modifying your existing equipment, this 100 Amp, 3-pole molded case circuit breaker is built to match the form, fit, and function of compatible Siemens ED frame installations. That means less guesswork during maintenance and greater confidence that the replacement will integrate with your existing electrical distribution system.

Inside, the thermal-magnetic trip unit automatically responds to both prolonged overloads and short circuits, helping protect connected equipment while keeping your system operating as intended. Rated for 480V AC with an 18kA interrupting capacity, the ED43B100 is commonly found in commercial buildings, industrial facilities, manufacturing operations, and other demanding low-voltage applications.
