Siemens 3VA1 IEC frame 160, breaking capacity class H, Icu=70kA @ 415V, 4-pole, line protection TM240, In=25A, overload Ir=18A...25A, short-circuit Ii=6.4...12.8 x In, N conductor protection 100%, nut keeper kit for DC Power OEM in China.
The rated current In is 25 A, with overload protection adjustable from 18 A to 25 A and short-circuit protection set between 6.4 and 12.8 times In. This variant includes 100% N conductor protection and a nut keeper kit, specified for a DC Power OEM in China.
The TM240 thermal-magnetic trip gives a fixed magnetic pickup, so coordination studies need to account for the 6.4–12.8x In range. The nut keeper kit is a mechanical accessory for secure mounting in OEM builds.
The breaking capacity class H provides an Icu of 70 kA at 415 V under IEC 60947-2, suitable for high-fault-current applications.
