The Siemens 3VA1132-4EF36-0CC0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, 3-pole, with a continuous current of 32 A at 40 °C and a breaking capacity of 121 kA at 240 V AC. It carries an undervoltage release and two auxiliary switches HQ, and its 70 mm depth fits standard panel layouts.
Breaking capacity and thermal derating
The 3VA1132-4EF36-0CC0 delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — enough for high-fault utility feeds or transformer secondaries. The thermal rating holds at 32 A up to 50 °C, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C, so a warm enclosure doesn't force a frame-size jump unless ambient exceeds 70 °C.
Dimensions and panel fit
At 70 mm deep × 76.2 mm wide × 130 mm high, this MCCB fits standard DIN-rail or screw-mount panel layouts. The 3-pole width matches the common 3-module footprint; the 70 mm depth clears most gland-plate or back-panel clearances without crowding.
