The design includes phase failure detection and a factory-fitted shunt trip (STL) for remote tripping, but no auxiliary switch or undervoltage release. At 400 A, this MCCB handles the full-load current of a large motor or a feeder feeding multiple smaller motors. Maximum power loss is 63.5 W, a figure to factor into enclosure thermal calculations. The shunt trip (STL) allows a remote signal (e.g., from an E-stop or PLC) to open the breaker independently of the overcurrent trip mechanism. No auxiliary contacts are included, so if you need status feedback to a control system, plan for an external auxiliary switch block. ## Interrupting Capacity — Where It Fits At 415 V (common in European industrial), 121 kA covers most utility-fed plant mains. ## Integration Notes Dimensions are 248 mm high × 138 mm wide × 110 mm deep (9.76 × 5.43 × 4.33 in). The 3-pole footprint matches the standard SENTRON 3VA frame; panel cutout and mounting hole pattern follow the 3VA family template. The breaker ships as a basic switch (base order code 3VA2440-5MN32-0AA0) with the shunt trip added.","metaTitle":"Siemens 3VA2440-5MN32-0HA0 SENTRON MCCB, 400 A, 3-Pole, Moto","metaDescription":"Siemens SENTRON 3VA2440-5MN32-0HA0 molded case circuit breaker, 400 A rated at 40 °C, 3-pole, motor protection design with shunt trip (STL). 187 kA at 240 V.
