Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. At typical 400 V industrial distribution, that 121 kA rating handles high-fault scenarios common behind large step-down transformers. The shunt trip lets a remote PLC or safety relay drop the breaker on command, which is standard for emergency-stop circuits or interlocked machine zones. Dimensions are 248 mm high × 138 mm wide × 110 mm deep (9.76 × 5.43 × 4.33 in). The 110 mm depth is a standard panelboard fit — check gland-plate clearance if back-panel wiring is tight. Three-pole configuration with phase failure detection built in; undervoltage release is not fitted on this variant. ## Key Specifications Power loss at maximum rating is 63.5 W — account for that in panel thermal calculations if multiple breakers are ganged. The short-time withstand rating is limited to 5 kA for 1 s. This is the motor protection design variant, not a standard feeder breaker. The internal electronic trip unit includes phase failure detection to protect three-phase motors from single-phasing.","metaTitle":"Siemens 3VA2440-5MN32-0JC0 SENTRON MCCB, 400 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2440-5MN32-0JC0 SENTRON molded case circuit breaker, 400 A continuous at 70 °C, 187 kA at 240 V, 3-pole motor protection with shunt trip and auxiliary switches.
