Siemens EF3M020 – 20A 3 Pole Molded Case Circuit Breaker Last Chance

Designed for heavy-duty power distribution, the Siemens EF3M020 is a 20-amp, 3-pole molded case circuit breaker. It utilizes fixed thermal-magnetic trip technology to deliver consistent long-time and instantaneous protection. This E-Frame breaker mounts into Siemens P1, P2, and P3 panelboards, offering seamless integration for existing infrastructure. For modern upgrades, this unit crosses over to the ED63B020 replacement. It features a 600VAC rating with a 14kAIC capacity at 480V.
