SENTRON 3VA1132-5EF32-0AE0 — 32 A MCCB, 3-Pole, TM240 Release
The Siemens SENTRON 3VA1132-5EF32-0AE0 is a 3-pole molded case circuit breaker rated for 32 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release. The TM240 release gives you a fixed thermal trip curve and magnetic short-circuit response, no interchangeable trip units to swap out. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. At 690 V, the 17 kA rating still covers most industrial networks in that voltage class. Power loss runs 10.6 W max at rated current — negligible for panel thermal budgeting, but worth noting if you're packing multiple breakers in a sealed enclosure.
Above that, it derates: 31 A at 55 °C, 31 A at 60 °C, 30 A at 65 °C, and 30 A at 70 °C.
Auxiliary Switching and Lifecycle
If you need those, you're looking at a different suffix in the 3VA1 family. Communication function is absent here — it's a standalone thermal-magnetic breaker, not a metering or communicating device.
