Rated operational current 8 A, and at AC-3 duty at 400 V it holds that same 8 A rating — no derating for motor switching. The instantaneous short-circuit trip responds at 104 A, magnetic type, so it clears hard faults fast without thermal delay. Mounting position any — vertical, horizontal, upside down, no restriction. Dimensions 45 mm wide, 97 mm high, 96 mm deep — fits standard S00 footprint. For a panel built around a 3RV6011-0CA10, this drops in place without rewiring: same frame size, same terminal arrangement, same rail clip. ## Electrical ratings in context Rated insulation voltage 690 V AC with pollution degree 3, same as the rated operational voltage maximum. Surge voltage resistance 6 kV — adequate for 400 V line-to-line panels with standard overvoltage category III. Operating frequency at AC-3 limited to 15 switching operations per hour; that's the thermal limit of the bimetal, not a wear-out figure. Power loss 7 W total typical — negligible for panel thermal budget but relevant if tightly enclosed. Terminal capacity: 2x 0.75–2.5 mm² solid/stranded, or 2x 4 mm² solid; AWG 2x 18–12 for main contacts. Torque 0.8–1.2 N·m on the screw terminals.","metaTitle":"Siemens 3RV6311-1HC10 SIRIUS Circuit Breaker, 8 A AC-3, 690","metaDescription":"Siemens 3RV6311-1HC10 SIRIUS circuit breaker for starter combinations. 8 A AC-3 at 400 V, 690 V insulation, screw terminals, snap-on DIN rail.
