For the main power circuit, the contactor is rated 10 A in AC-12 duty (resistive loads at line frequency). That is the continuous current limit for general switching; for motor loads the rating depends on duty cycle and voltage — at 500 V the contactor handles 4.5 kW in AC-3 duty, and at 690 V it handles 5.5 kW. The AC-4 rating (plugging / inching) at 400 V is 8.5 A, so if your application requires frequent reversals, that figure governs the thermal limit, not the AC-12 number. Auxiliary contacts are rated for switching at multiple control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC. The DC switching capacity drops sharply with voltage — the 220 V DC rating of 0.3 A reflects the arc-extinction limits of the air gap, so do not assume the AC rating carries over to DC circuits. For type 2 coordination (contactor remains operable after a fault) the requirement is a 20 A gL/gG fuse. The terminal block accepts solid or stranded conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or a maximum of 2x 0.75–4 mm² per clamp. ## Environmental limits and mounting The enclosure is rated IP20 on the front and at the terminals — finger-safe but not protected against moisture ingress, so it belongs inside a sealed panel, not on an open machine frame.","metaTitle":"Siemens 3RT1016-1DB44-0KV0 SIRIUS Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-1DB44-0KV0 power contactor, size S00, 24 VDC coil, integrated varistor.
