ED63B020 - 20Amp Circuit Breaker

ED63B020 - 20Amp Circuit Breaker

Keeping an electrical system operating safely often comes down to using the right replacement components. The Siemens ED63B020 is a 20 Amp, 3-pole molded case circuit breaker designed for compatible Siemens SENTRON ED Frame installations where dependable circuit protection and proper equipment compatibility matter. Featuring a thermal-magnetic trip unit, this breaker responds to both sustained overloads and short-circuit conditions, helping protect electrical equipment while maintaining the original design of your distribution system.

Built for applications rated up to 600VAC, the ED63B020 provides an interrupting capacity of 18kA at 600VAC and 25kA at 480VAC, making it suitable for many commercial and industrial power distribution systems.
