Interrupting capacity steps with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. For a 480 V distribution panel (common in North American industrial), the 440 V figure is the closest proxy — 32 kA SCCR headroom covers most transformer-fed secondary buses. The TM240 thermal-magnetic release provides fixed short-circuit and overload protection; no communication, no ground-fault module, no auxiliary contacts on this variant. ## Shunt trip and auxiliary release No undervoltage release, no auxiliary contact block on this build. If the BOM calls for remote undervoltage protection or status feedback, the base breaker won't deliver it without adding the separate module.","metaTitle":"Siemens 3VA1112-3EF36-0JA0 SENTRON MCCB, 125 A, 75.6 kA","metaDescription":"Siemens 3VA1112-3EF36-0JA0 SENTRON molded case circuit breaker, 125 A rated, 75.6 kA at 240 V interrupting capacity.
