The Siemens SENTRON 3VA1216-5EF32-0CA0 is a 3-pole molded case circuit breaker rated 160 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release. That 160 A holds flat through 50 °C and only begins to derate above 55 °C — at 70 °C it still delivers 142 A, which matters if this breaker lives in a hot panel near drives or transformers. An integrated undervoltage release (UVR) is part of the build — this breaker drops open if control voltage is lost, which is typical for emergency-stop and safety isolation circuits. No communication module or ground-fault monitoring on this variant.
Power loss is 35.5 W maximum; that heat has to be accounted for in the enclosure thermal budget. The 70 mm depth keeps it within the envelope of most distribution panels without crowding the gland plate.
Coordination notes
Rated insulation voltage 800 V, rated impulse withstand voltage 8 kV (typical for this class). The TM240 release is a fixed thermal-magnetic — no interchangeable trip unit, so the 160 A rating is baked into this order code.
