ED63B090L - 90Amp Circuit Breaker

ED63B090L - 90Amp Circuit Breaker

When you're replacing a circuit breaker in an existing Siemens electrical distribution system, choosing the correct part number is essential. The Siemens ED63B090L is a 3-pole, 90 Amp molded-case circuit breaker from the SENTRON ED Frame family, designed as a form, fit, and function replacement for compatible Siemens equipment. Featuring a thermal-magnetic trip unit, this breaker helps protect electrical systems from overloads and short circuits while maintaining the original design and operating characteristics of your installation.

One feature that sets the ED63B090L apart is its factory-installed line and load side lugs (LN1E100), allowing both incoming and outgoing conductors to be terminated directly to the breaker. The lugs accept 10 AWG through 1/0 AWG copper or aluminum conductors, providing flexibility for compatible installations and maintenance projects. Whether you're replacing a failed breaker or performing routine maintenance, the Siemens ED63B090L delivers the proper ratings, compatibility, and dependable protection expected from the SENTRON ED Series.
