32 A MCCB with TM240 release — line protection for 3-pole panels
The Siemens 3VA1132-3EF36-0JC0 is a SENTRON molded case circuit breaker (MCCB) rated for 32 A continuous current at 40 °C, with a 3-pole configuration and a TM240 thermal-magnetic overcurrent release. The interrupting ratings climb to 75.6 kA at 240 V and still hold 10.5 kA at 690 V, so it clears high-fault scenarios across common low-voltage distribution voltages. Front face carries IP40 protection; the housing dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — standard DIN-rail or screw-mount footprint for a 3-pole MCCB in a panel enclosure.
Derating curve and thermal limits
Above that, it steps down: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. The depth of 70 mm and width of 76.2 mm fit standard 3-pole MCCB mounting footprints — check gland-plate clearance if the panel has shallow back-panel wiring troughs.
Auxiliary and trip options on this variant
The auxiliary release design is identified as 3VA9688-0BL32. Mechanical endurance is listed at 15,000 operations.
