The In=100A continuous rating and Ir adjustable from 70A to 100A let you dial in the overload pickup to match the cable or load — common for motor branch circuits or feeder protection where the exact FLA lands inside that window. The Ii fixed at 10 x In (1000A) means magnetic trips happen fast on hard faults, but won't nuisance-trip on moderate inrush. For a 415V distribution board with available fault current under 25kA, this breaker coordinates cleanly downstream of a current-limiting fuse or upstream breaker. The N conductor is unprotected on this variant, so it tracks the phase protection but doesn't have its own overload element — standard for balanced 3-phase loads where the neutral carries only imbalance current. The nut keeper kit for DC Power OEM in China suggests this specific variant was configured for a DC power OEM application — verify the DC rating curve if using on DC circuits, as the thermal-magnetic trip is calibrated for AC 50/60 Hz waveforms.","metaTitle":"Siemens 3VA1110-3EE42-0AA0-ZD00 Circuit Breaker, 100A, 25kA","metaDescription":"Siemens 3VA1110-3EE42-0AA0-ZD00 IEC frame 160 circuit breaker, 4-pole, 100A, 25kA breaking capacity at 415V.
