Front protection is IP40; the enclosure is sized at 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint that fits most SENTRON panelboards without re-drilling. Above that, the breaker derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If the panel ambient runs near 60 °C, plan for a 3 A reduction — or step up one frame size if the load is continuous at 50 A. ## Integrated shunt trip and auxiliary provisions This variant ships with a factory-integrated shunt trip (STL) — design order code 3VA9688-0BL33 — for remote opening via a control voltage. No undervoltage release, no auxiliary contact, and no communication module are fitted. The breaker has a voltage trigger (shunt trip) but no phase-failure detection or ground-fault monitoring.","metaTitle":"Siemens 3VA1150-5EF36-0KA0 SENTRON MCCB, 50 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-5EF36-0KA0 molded case circuit breaker, 50 A rated continuous current, 187 kA breaking capacity at 240 V.
