ED23B070 - 70Amp Circuit Breaker

ED23B070 - 70Amp Circuit Breaker

When replacing a breaker in an existing Siemens electrical distribution system, choosing the correct form, fit, and electrical rating is essential. The Siemens ED23B070 is a 70 Amp, three-pole thermal magnetic molded case circuit breaker designed for use in Siemens SENTRON ED-frame panelboards and distribution equipment. Built for dependable overcurrent protection, this breaker helps maintain the original configuration of compatible systems while providing the protection needed for everyday commercial and industrial applications.

Whether you're performing scheduled maintenance or replacing an existing breaker, this model is designed to match the original installation without requiring changes to the panel configuration.

This Siemens ED-frame breaker features a 10kA interrupting capacity at 240VAC and comes with factory-installed load-side lugs (LN1E100) that accept 10 AWG through 1/0 AWG copper or aluminum conductors.
