The shunt trip (STL) operates on 12–30 V DC or 24 V AC, so it integrates with a 24 V DC safety circuit or a separate control transformer without an interposing relay. For a 415 V panel with a transformer rating above 2 MVA or a utility fault current near 50 kA, this unit provides the headroom to avoid cascading failure upstream. The fixed Ir=63 A and Ii=10 x In mean the instantaneous pickup is at 630 A; that suits motor or transformer feeder protection where a lower magnetic trip would nuisance-trip on inrush. The TM210 thermal curve is a standard inverse-time characteristic for cable and general distribution protection. ## Panel integration Shunt trip wiring lands on the accessory terminals; polarity matters for the DC supply, so verify the 12–30 V DC connection before energizing.","metaTitle":"Siemens 3VA1163-5ED32-0HA0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5ED32-0HA0 IEC frame 160 circuit breaker, 3-pole, 63A TM210 overload, 55kA breaking capacity at 415V.
