Its headline breaking capacity is Icu=55kA at 415V AC — class M in the 3VA2 family, meaning it handles high fault currents typical of industrial main feeders or large distribution panels. The LSI protection profile (Long-time, Short-time, Instantaneous) gives you adjustable overload Ir=400A...1000A, short-circuit pickup Isd=1.5...10 x Ir, and a fixed instantaneous Ii=10 x In. The N-conductor protection is adjustable OFF/50%/100%. The nut keeper kit is factory-installed, which simplifies panel assembly: no loose hardware to drop into live gear during installation.","metaTitle":"Siemens 3VA2510-5HN42-0KH0 3VA2 IEC Breaker, 1000A, 55kA @ 4","metaDescription":"Siemens 3VA2510-5HN42-0KH0 circuit breaker, 3VA2 IEC frame 1000, 55kA @ 415V, 4-pole, ETU350 LSI, In=1000A, shunt trip 208-277V AC, 2 aux switches.
