That makes it a fast-moving standard spare for line protection applications where you don't need the flexibility of an electronic trip. The breaker carries four HQ auxiliary switches (2 NO + 2 NC) built in, so you get status feedback without adding a separate aux block. Above that, it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C.","metaTitle":"Siemens 3VA1140-5EF32-0AE0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1140-5EF32-0AE0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, TM240 thermal-magnetic release, 187 kA breaking at 240 V.
