Siemens 3VA1 IEC frame 160, breaking capacity class M, Icu=55kA @ 415V, 3-pole, line protection TM240, ATAM, In=160A, overload protection Ir=112A...160A, short-circuit protection Ii=5...10 x In, clamp connection, undervoltage release (UVR) 120-127V AC 50/60Hz, 2 auxiliary switches HQ, 1 trip alarm switch HQ.
Overload protection (Ir) is adjustable from 112 A to 160 A via the ATAM dial; short-circuit protection (Ii) is fixed at 5 to 10 times In, so a 160 A breaker trips magnetically between 800 A and 1600 A. The built-in undervoltage release (UVR) operates on 120–127 V AC, 50/60 Hz — common for North American control voltages stepped down from a 480 V panel.
The breaking capacity class M gives Icu = 55 kA at 415 V AC, suitable for high-fault-current industrial mains.
