The Siemens SENTRON 3VA1132-6EF32-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated for 32 A continuous current, with a TM240 thermal-magnetic overcurrent release. It's built for line protection — meaning it sits upstream protecting a feeder or distribution bus, not a specific motor or drive load. The 220 kA breaking capacity at 240 V tells you this breaker can interrupt a massive fault without welding its contacts or blowing apart; at 415 V it still handles 154 kA, and even at 690 V it holds 17 kA. That kind of short-circuit rating is what you spec when the available fault current at the panel is high — say, close to a large transformer.
Thermal derating and operating range
This breaker carries its full 32 A rating from 40 °C up to 50 °C. At 55 °C it derates to 30.72 A, and at 70 °C — the top of its operating range — it's at 28.8 A. The operating ambient spans -25 °C to 70 °C, with storage from -40 °C to 80 °C. If your panel runs hot (say, inside a non-ventilated enclosure near a furnace line), you'll need to account for that derating curve. The IP40 on the front means it's protected against tools and wires over 1 mm, but not against water spray — keep it inside the enclosure, not on a wet floor.
Auxiliary contacts and shunt trip
It ships with 2 auxiliary switches plus a separate trip alarm switch (HQ type). That's enough for a remote status indication — say, a PLC input for 'breaker closed' and another for 'breaker tripped' — plus a spare for something else. The shunt trip (STL) release is built in, so you can trip the breaker remotely via a control signal. No undervoltage release, no ground-fault monitoring, no communication module on this variant.
