Siemens 3VA2 series, IEC frame 630, breaking capacity class M, 3-pole circuit breaker, 400 A, Icu=55 kA @ 415 V, ETU350 LSI trip unit, universal release 24 V DC, 2 auxiliary switches + 1 trip alarm switch.
The Siemens 3VA2440-5HN32-0LJ0 is a 3-pole IEC frame 630 circuit breaker in the 3VA2 series, rated for line protection with an ETU350 LSI trip unit.
Rated In=400 A, with overload protection Ir adjustable from 160 A to 400 A, short-circuit protection Isd from 1.5 to 10 x Ir, and instantaneous pickup Ii fixed at 12 x In.
The part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Icu=55 kA at 415 V (breaking capacity class M), which is the maximum fault current the breaker can safely interrupt at that voltage.
An ETU350 LSI electronic trip unit with adjustable overload (Ir=160-400 A), short-delay (Isd=1.5-10 x Ir), and instantaneous (Ii=12 x In) protection curves.
