Depth is 72 mm, so watch the gland-plate clearance if you're mounting it near the back of a shallow enclosure. Side-by-side mounting is allowed with a 6 mm gap at the side — no derating required for adjacent units as long as that spacing is kept. ## Switching capacity and coordination The contactor's switching current depends on the voltage you're working with. At 24 V it handles 10 A; at 60 V it's 2 A; at 110 V it's 1 A; at 220 V it's 0.3 A; at 230 V it's 6 A; at 400 V it's 3 A. Type 1 coordination calls for a 35 A gL/gG fuse; Type 2 coordination needs a 20 A gL/gG fuse. That's the fuse size to spec if you want the contactor to survive a short circuit without replacement.","metaTitle":"Siemens 3RT1317-1BW40 SIRIUS S00 Power Contactor, 4 NO, 24 V","metaDescription":"Siemens 3RT1317-1BW40 SIRIUS S00 power contactor, 4 NO main contacts, 24 VDC coil, 5.5 kW at 400 V AC-2.
