It is a straightforward, high-interrupting-capacity main or feeder breaker for panels where remote shunt-trip capability is needed and auxiliary signaling is handled externally. Above that, derating is gradual: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. For a panel builder sizing a 40 A feeder in a warm enclosure, the margin at 50 °C is comfortable — no upsize needed. The breaker measures 76.2 mm wide, 130 mm high, and 70 mm deep, with IP40 protection on the front. The 70 mm depth is compact enough for standard 200 mm deep enclosures; the 76.2 mm width (roughly 3 inches) fits a 3-pole MCCB footprint common across the SENTRON 3VA platform. The part carries a latching endurance of 15,000 cycles, which governs mechanical life under normal switching — not a daily-switch duty class, but adequate for infrequent isolation and fault clearing.","metaTitle":"Siemens 3VA1140-5EF36-0JA0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1140-5EF36-0JA0 SENTRON molded case circuit breaker, 40 A rated continuous current, 3-pole, TM240 thermal-magnetic release, 187 kA breaking capacity at 240 V.
