ED41B070 - 70Amp Circuit Breaker

ED41B070 - 70Amp Circuit Breaker

Looking for a replacement breaker that fits your existing 277V electrical system? The Siemens ED41B070 is a 70 Amp, single-pole molded case circuit breaker designed to provide dependable branch circuit protection while maintaining compatibility with existing Siemens ED-frame equipment. Commonly found in commercial and industrial electrical systems, this breaker is intended for maintenance and replacement applications where preserving the original panel configuration is important.

The ED41B070 features a thermal magnetic trip unit that combines inverse-time overload protection with instantaneous short-circuit response. This proven design helps protect conductors and connected equipment from common overcurrent conditions encountered during everyday operation. With a 22kA interrupting capacity at 277V AC, it is intended for installations where the available fault current does not exceed its interrupting rating.
