Its interrupting ratings are the headline: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that place it in the high-breaking-capacity class for industrial distribution where fault currents can exceed 100 kA on the secondary side of a large transformer. ## Panel fit and auxiliary contacts The 3VA1110-5EF36-0AC0 measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint that fits Siemens SENTRON mounting plates and most DIN-rail adapters. Front protection is IP40, meaning tools or fingers cannot reach live parts from the front, but the sides and back are open for heat dissipation inside the enclosure — standard for panel-mounted MCCBs. ## Lifecycle and compliance posture Storage temperature range of -40 °C to 80 °C and operating range of -25 °C to 70 °C cover most indoor and conditioned outdoor installations; the -25 °C minimum means it can sit in an unheated electrical room in cold climates without issue.","metaTitle":"Siemens 3VA1110-5EF36-0AC0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1110-5EF36-0AC0 molded case circuit breaker, 3-pole, 100 A, TM240 release, 187 kA at 240 V.
