Short-circuit protection requires a gL/gG fuse: 20 A for type 2 coordination (no welding after fault), 35 A for type 1 (welding allowed but no fire risk). The coil is DC-operated with a closing and holding power of 3.3 W, rated at 220 V DC. ## Termination and mounting Screw terminals accept solid or finely stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). AWG equivalents for main contacts are 2x (20 to 16), 2x (18 to 14), or 1x 12. Maximum installation altitude is 2 000 m above sea level.","metaTitle":"Siemens 3RT1317-1BM40 SIRIUS Power Contactor, 4 NO, 5.5 kW A","metaDescription":"Siemens SIRIUS power contactor 3RT1317-1BM40, size S00, 4 NO main contacts, 5.5 kW at 400 V AC-2, IP20 screw terminals, active production.
