The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V, which covers most industrial distribution panels without needing a current-limiting upstream device. Above that it steps down: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that clips onto DIN rail or mounts with screws to a backplate. The 4 HQ auxiliary switches give you two form-C contacts for status to a PLC and two for a local indication lamp, all without an add-on module.","metaTitle":"Siemens 3VA1140-5EF36-0AE0 SENTRON MCCB, 40 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1140-5EF36-0AE0 molded case circuit breaker, 40 A rated, TM240 release, 3-pole, 187 kA interrupting at 240 V.
