Siemens 3VA1 IEC frame 160 circuit breaker, 4-pole, breaking capacity class N, Icu=25kA @ 415V, TM210 line protection, In=160A, Ir=160A fixed, Ii=10 x In, N conductor protection 100%, nut keeper kit, DC Power OEM in China.
It's rated for a breaking capacity of 25 kA at 415 V (class N), with a fixed 160 A thermal-magnetic overload (TM210) and fixed short-circuit pickup at 10 x In.
The fixed Ir=160 A means no adjustment dial; you size the breaker to the load, not the other way around. Fixed Ii=10 x In (1600 A magnetic trip) suits motor or transformer inrush without nuisance tripping, but won't coordinate with a feeder breaker that has a lower instantaneous threshold — check your selectivity study.
This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
