MCCB for high-fault panel lines
The Siemens 3VA1132-6EF36-0JA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a 32 A continuous rating at 40 °C and a 3-pole configuration, with a TM240 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. Interrupting capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — that's high-fault headroom for main or feeder duty where the available fault current is substantial. At 500 V and 690 V it still holds 17 kA, which covers most industrial motor-control panels. Rated insulation voltage is 800 V. Power loss at full load is 10.6 W.
Mounting and panel fit
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. 3-pole configuration. The shunt trip release (STL) is factory-installed, so no field wiring of a separate trip coil is needed. Undervoltage release is not present on this variant — if you need UVR, that's a different order code.
