Rated for 10 A at 24 V, 6 A at 230 V AC, and 3 A at 400 V AC — these are the thermal continuous currents the contacts can carry in their respective voltage classes. At 110 V the rating drops to 1 A, at 220 V to 0.27 A, at 500 V to 2 A, and at 690 V to 1 A, reflecting the arc-quenching limits of the contact gap at higher potentials. Shock resistance is rated at 10g for 5 ms and 5g for 10 ms, sufficient for installation on vibrating machinery or in panels mounted on pump skids. Mechanical endurance is 30 million operating cycles typical, which for an auxiliary contactor used in signal switching translates to years of service in most production lines. ## Wire termination Terminals accept solid conductors: two wires of 0.5–1.5 mm², two of 0.75–2.5 mm², or two of 4 mm² — the dual-wire capacity simplifies daisy-chaining control voltage or commoning multiple contacts without extra terminal blocks.","metaTitle":"Siemens 3RH1140-1AP00-0TK0-ZX95 SIRIUS Auxiliary Contactor,","metaDescription":"Siemens SIRIUS 3RH1140-1AP00-0TK0-ZX95 auxiliary contactor, size S00, 4 NO contacts, 10 A at 24 V, screw/snap-on mount, IP20 front.
