Its interrupting capacity is what drives the selection: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V — so the same breaker covers high-fault residential services and industrial 480Y/277 V panels where fault current runs 100 kA+. ## Thermal derating and power loss That matters in a crowded panel where internal temperature hits 60 °C — you still get 48 A of headroom. Maximum power loss is 14.6 W, which is low enough that adjacent DIN-mounted devices don't need forced air in most enclosures. ## Built-in auxiliary and trip signaling The trip indicator and voltage trigger are standard — so a PLC or SCADA system gets both position feedback and a dedicated fault signal without adding external relays.","metaTitle":"Siemens 3VA1150-5EF36-0HH0 SENTRON MCCB, 50A, 3-Pole, 187kA","metaDescription":"Siemens 3VA1150-5EF36-0HH0 SENTRON molded case circuit breaker, 50A rated, 3-pole, 187kA SCCR at 240V.
