Siemens 3VA1 IEC frame 160 circuit breaker, 4-pole, breaking capacity class N, Icu=25kA @ 415V, In=63A, overload protection Ir=44A..63A, short-circuit protection Ii=10 x In.
Overload protection (Ir) is adjustable from 44 A to 63 A via the TM220 dial, letting you match the breaker to the actual load current without swapping trip units. Short-circuit protection (Ii) is fixed at 10 x In (630 A), which is typical for thermal-magnetic breakers on motor or general distribution circuits — fast enough to clear bolted faults but coordinated downstream for selective tripping.
