The Siemens 3VA1096-3ED32-0BA0 is a 3-pole IEC frame 100 circuit breaker with a 25 kA breaking capacity at 415 V (class N). It's set up for fixed line protection: thermal overload fixed at 16 A (Ir), magnetic short-circuit pickup fixed at 10 x In (160 A). The TM210 release curve means it's a thermal-magnetic trip — no electronic adjustment, no messing with dials.
This breaker includes a nut keeper kit and an undervoltage release (UVR) coil at 24 V DC. The UVR drops the trip mechanism if control voltage falls below dropout — standard for emergency-stop circuits or upstream contactor interlocking. Mounts on a DIN rail in the panel; the nut keeper keeps the busbar connection hardware from backing out under vibration.
