Siemens EF3B070 – 70A 3 Pole Molded Case Circuit Breaker Trending

Built for commercial and industrial power distribution, the Siemens EF3B070 delivers robust long-time and instantaneous trip functions. This 70A, 3-pole device belongs to the legacy E-frame family of molded case circuit breakers. It mounts into older Siemens and I-T-E panelboards or switchboards requiring a bolt-on connection. While this specific unit is a legacy model, it is commonly replaced by the newer ED63B070 frame. Featuring a non-interchangeable trip unit, it handles 18kAIC at 240V.
