SENTRON 3VA 32 A MCCB — line protection with TM240 release
It carries a 75.6 kA interrupting capacity at 240 V, stepping down to 52.5 kA at 415 V and 32 kA at 440 V — enough headroom for most industrial distribution panels where fault currents are coordinated upstream. The TM240 thermal-magnetic release means the thermal element tracks the cable temperature curve for overload protection, while the magnetic instantaneous element clears short-circuit faults fast. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3VA frame size that fits the SENTRON mounting base and busbar system. The 2 auxiliary switches HQ are built in, so you get status feedback without adding external contact blocks.
The interrupting ratings are voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Power loss is 10.6 W maximum at rated load — manageable for panel thermal budgeting.
