It's designed for line protection in distribution panels, with a 440 kA breaking capacity at 415 V and 187 kA at 690 V — enough to handle high-fault utility feeds without cascading upstream breakers. That means it catches phase-to-ground faults without a separate GFCI module — a space saver on the DIN rail. At 86 mm deep, 105 mm wide, and 181 mm tall, this MCCB fits standard SENTRON 3VA2 panel cutouts. Power loss is 1.2 W maximum at rated load, so thermal rise inside a dense panel is minimal — no special derating needed for adjacent breakers in a standard 40 °C ambient.","metaTitle":"Siemens 3VA2140-0HM32-0AA0 SENTRON MCCB, 40 A, 3-Pole, 440 k","metaDescription":"Siemens 3VA2140-0HM32-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 3-pole, ETU330 trip unit, 440 kA breaking capacity at 415 V.
