Siemens 3VA1 IEC frame 630 circuit breaker, breaking capacity class C, Icu=110kA @ 415 V, 4-pole, line protection TM220, ATFM, In=500A, overload protection Ir=350A...500A, short-circuit protection Ii=10 x In, N conductor unprotected, nut keeper kit.
The Siemens 3VA1450-7EE42-0AA0 is a 4-pole IEC frame 630 circuit breaker with a class C breaking capacity of 110 kA at 415 V. It carries a TM220 ATFM trip unit, with overload protection adjustable from 350 A to 500 A and fixed short-circuit protection set at 10 times the rated current (Ii = 10 x In).
The TM220 thermal-magnetic trip provides inverse-time overload protection (Ir = 350–500 A) and instantaneous short-circuit protection at 5000 A (10 × 500 A).
The 3VA1450-7EE42-0AA0 has a class C breaking capacity Icu = 110 kA at 415 V.
The TM220 ATFM trip unit provides overload protection adjustable from 350 A to 500 A (Ir).
