Siemens 3VA1 IEC frame 100 circuit breaker, 4-pole, 25 A, breaking capacity class B Icu=16 kA @ 415 V, TM210 line protection, FTFM, Ir=25 A fixed, Ii=12.8 x In, N conductor unprotected, nut keeper kit for DC Power OEM in China.
The Siemens 3VA1025-2ED42-0AA0-ZD00 is a 4-pole IEC frame 100 circuit breaker rated 25 A with a breaking capacity of 16 kA at 415 V (class B). It uses a TM210 thermal-magnetic trip unit — overload protection set fixed at Ir = 25 A, short-circuit protection fixed at Ii = 12.8 × In.
The fixed Ir and Ii settings mean no adjustment dials — set-and-forget for OEM builds where the load is known at design time.
The breaking capacity is Icu = 16 kA at 415 V, class B per IEC 60947-2, which means it can safely interrupt fault currents up to that level without upstream cascading.
