The Siemens 3VA1096-4ED32-0HA0 is a 3-pole IEC frame 100 circuit breaker from the 3VA1 series, rated at 16 A with a fixed thermal-magnetic overload (TM210) and a fixed short-circuit protection set at 10 x In. Its breaking capacity class S delivers 36 kA at 415 V AC — enough to handle high-fault-current panel feeds without cascading upstream. The integrated shunt trip (STL) operates on 12–30 V DC or 24 V AC, so it can be wired into a remote emergency-stop or undervoltage-release circuit. A nut keeper kit is included for secure DIN-rail mounting.
What the ratings mean for your panel
The 36 kA Icu at 415 V is the maximum short-circuit current this breaker can safely interrupt under IEC 60947-2. In a typical 400 V distribution board, that SCCR headroom means you can place it downstream of a transformer or main breaker without worrying about fault current exceeding the device's rating — as long as the prospective short-circuit current at its location stays under 36 kA. The fixed Ir=16 A overload matches a 16 A feeder or motor branch; the Ii=10 x In (160 A magnetic trip) clears bolted faults fast, but for motor-starting inrush you'd want to verify the curve doesn't nuisance-trip on your load. The shunt trip coil is rated for 12–30 V DC and 24 V AC 50/60 Hz — a wide DC range that covers common 24 V control supplies and allows a drop to 12 V in battery-backed safety circuits. It's a separate order from the breaker body; the nut keeper kit is included in this variant.
