This MCCB mounts in a standard panel enclosure — the 76.2 mm width (roughly 3 inches) fits a 3-pole footprint, and the 70 mm depth keeps it within typical distribution board clearances. The shunt trip (STL) release (order code 3VA9688-0BL32) enables emergency-off or remote-trip integration into a safety circuit or PLC-driven shutdown. Above that, derate linearly: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If the panel runs hot — near a drive cabinet or in a non-ventilated enclosure — factor the 55 °C derating into your load calculation. ## Integration notes — shunt trip and auxiliary contacts The shunt trip release (STL) is factory-integrated — order code 3VA9688-0BL32 for the release module itself if servicing a panel that already has the breaker. The undervoltage release is also absent; this breaker trips only on overcurrent or via the shunt trip signal.","metaTitle":"Siemens 3VA1050-2ED32-0JA0 SENTRON MCCB, 50 A, 3-Pole, 52.5","metaDescription":"Siemens SENTRON 3VA1050-2ED32-0JA0 molded case circuit breaker, 50 A rated continuous current, 3-pole, 52.5 kA breaking capacity at 240 V.
