Siemens 3VA5110-5EC31-0AA0 100A 3P Molded Case Circuit Breaker – Panel Mount – 480V AC

The Siemens 3VA5110-5EC31-0AA0 is a 100A, 3-pole molded case circuit breaker from the SENTRON 3VA5 series, designed for commercial and industrial power distribution systems. It features a TM230 thermal-magnetic trip unit with fixed thermal and adjustable magnetic (LI) protection, enabling improved coordination and flexibility for downstream protection.

Built for Siemens P1, P2, and P3 panelboards as well as switchboards and motor control centers, this breaker is suitable for retrofit and new installations, including replacements for legacy ED63B100 and ED43B100 devices. Its Class M interrupting performance provides higher fault capacity compared to standard Class S variants.
