The DC magnet coil draws 3.3 W on closing and holds at the same 3.3 W — a constant-hold design that simplifies the control transformer sizing. Rated control supply voltage is 42 V DC. The pick-up threshold is 0.85 x rated voltage (about 35.7 V), and the drop-out is not explicitly stated but typical for this class is around 0.6 x rated. ## Switching capacity and coordination Switching capacity at 24 V DC is 10 A, dropping to 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — the inductive load curve typical for DC coils and solenoids. For AC-12 (resistive) use, the maximum operating current is 10 A. Short-circuit protection: with type 2 coordination, use a gL/gG fuse rated 20 A; with type 1, a 35 A fuse.","metaTitle":"Siemens 3RT1317-2BD40 SIRIUS Power Contactor, 4 NO, 5.5 kW A","metaDescription":"Siemens SIRIUS 3RT1317-2BD40 power contactor, size S00, 4 NO main contacts, 5.5 kW at 400 V AC-2, spring-loaded terminals, 45 mm wide, active production.
