The interrupting capacity is 75.6 kA at 240 V, dropping to 52.5 kA at 415 V and 32 kA at 440 V — sufficient for high-fault industrial services where fault current can exceed 50 kA. There is no announced phase-out or last-time-buy window. For a BOM freeze or MRO spare, this part is a standard catalog line, not a sunset item that requires obsolescence planning. ## Panel integration — what fits where The MCCB measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchgear cubicles without re-drilling. Maximum power loss is 25 W — account for this in thermal calculations for enclosed panels, especially when multiple breakers are ganged. The closest functional peer is the 3VA1110-5ED36-0AC0. Both are 3-pole SENTRON MCCBs with the same frame size and 100 A thermal rating. The -3EF36-0JC0 includes a shunt trip and two HQ aux switches as standard.","metaTitle":"Siemens 3VA1110-3EF36-0JC0 SENTRON MCCB, 100 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1110-3EF36-0JC0 molded case circuit breaker, 100 A rated at 40 °C, 3-pole, 75.6 kA interrupting at 240 V.
