ED63B020L - 20Amp Circuit Breaker

ED63B020L - 20Amp Circuit Breaker

If you're replacing a breaker in an existing Siemens system, the ED63B020L is designed to make that job straightforward. This 20 Amp, 3-pole molded case circuit breaker from the Siemens SENTRON ED Frame series is built for maintaining proper fit and function in compatible electrical distribution equipment, especially where matching the original breaker specs matters.

Inside, it uses a thermal-magnetic trip unit, giving protection against overloads and short circuits in everyday commercial and industrial power systems. It’s rated for 600VAC applications, with an interrupting capacity of 18kA at 600VAC and 25kA at 480VAC, making it suitable for a wide range of standard distribution setups where these ratings are required.

The ED63B020L is commonly used in commercial buildings, manufacturing facilities, HVAC systems, motor control centers, and other industrial environments where Siemens ED Frame breakers are already installed. Rather than changing system design, this breaker is intended to help keep existing equipment operating as originally configured.
