The Siemens 3VA1196-3EF32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated 16 A continuous at 40 °C ambient, with a TM240 thermal-magnetic overcurrent release. At 415 V it still clears 52.5 kA, and at 690 V it holds 11.9 kA, so the same unit works across common industrial voltages without swapping frames. Designed for line protection — not motor or feeder — the TM240 release means the thermal element tracks cable heating, and the magnetic trip handles short-circuit. It's a straight breaker for a distribution subfeed or a lighting panel where you need the interrupting capacity of a molded-case frame but don't need auxiliaries.
That's a tight thermal curve; you can size it for a 16 A continuous load in a ventilated panel without over-spec'ing the frame. Power loss maxes at 10.6 W, which is low enough that adjacent breakers in a multi-pole group don't need extra spacing. The 70 mm depth and 76.2 mm width match the standard SENTRON 3VA footprint — it drops into the same DIN-rail or screw-mount panel cutout as other 3VA three-pole frames. No rewiring if you're swapping from a 3VA1110-5ED32-0AA0; the lug spacing and terminal layout are identical across the family.
IP40 on the front — suitable for indoor panel mounting where no water spray or dust ingress is expected.
