Line protection MCCB — 32 A, 3-pole, high interrupting capacity
The Siemens SENTRON 3VA1132-6EF36-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current Iu of 32 A and a TM240 thermal-magnetic overcurrent release. It carries a 220 kA interrupting capacity at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that put it in the high-fault-current class for industrial distribution panels where available fault current is high and upstream breaker coordination demands a robust downstream device. The 70 mm depth and 76.2 mm width fit standard panel layouts without special adapters.
Ratings and what they mean for fit
Rated continuous current Iu of 32 A holds flat from 40 °C to 50 °C, then derates to 30.72 A at 55 °C and 28.8 A at 70 °C — so in a warm enclosure (say 55 °C ambient), plan for a 30 A load max. The 220 kA at 240 V is the highest short-circuit rating on this frame; at 415 V it still delivers 154 kA, enough for most European industrial mains. The TM240 release means thermal pickup is fixed at 32 A (the Iu rating) with magnetic trip set at 240 A — a typical motor or feeder protection curve. The undervoltage release (UVR) integrated as standard trips the breaker when control voltage drops, which is common in safety circuits or emergency-stop chains. Auxiliary contacts come as 2 auxiliary switches plus 1 trip alarm switch HQ (order code 3VA9608-0BB11 for the integrated auxiliary trip assembly).
Panel integration notes
Mounts on a DIN rail or panel-mount via the 3VA frame. The 76.2 mm width and 70 mm depth leave room for side-by-side breakers in a standard distribution board.
