The 24 VDC coil pulls in reliably across the 0.8–1.1 x Us range at 50/60 Hz. Spring-loaded terminals accept 2x (0.25–2.5 mm²) solid or stranded — no ring lugs needed, which shaves a few minutes per termination on a panel build. AC-12 at 10 A covers resistive loads like heater banks or control transformers. For motor switching on standard squirrel-cage induction motors, you would typically size by the AC-3 rating; this contactor's AC-3 capability is not listed in the spec set, so verify against your motor FLA. Coil operates at 24 VDC with a tolerance band of 0.8–1.1 x Us at 50 Hz and 0.85–1.1 x Us at 60 Hz. That means at 50 Hz the coil holds from about 19.2 V to 26.4 V; at 60 Hz the lower end tightens to 20.4 V. If your control supply is marginal or long cable runs cause voltage drop, factor the 60 Hz band. ## Mounting and wiring integration The spring terminals accept 0.25–2.5 mm² (AWG 24–14) solid or ferruled stranded, two conductors per clamp. Strip length around 8–10 mm; push the screwdriver into the square opening, insert the wire, release. No torque driver required, which speeds up panel wiring. Type 1 coordination calls for a 35 A gL/gG fuse upstream; Type 2 coordination requires 20 A. If your panel has a 20 A branch circuit, the Type 2 fuse protects the contactor under a short-circuit condition without damage.","metaTitle":"Siemens 3RT1316-2AF00 SIRIUS Contactor, 4 NO, 4 kW AC-2, 24","metaDescription":"Siemens SIRIUS 3RT1316-2AF00 power contactor, Size S00, 4 NO main contacts, 4 kW at AC-2 400 V, 24 VDC coil, spring terminals, DIN rail mount.
