The Siemens 3RT7014-1AP01 is a size S00 contactor with three normally open main contacts, rated for AC-3 switching duty up to 690 V. The AC-operated coil draws 0.8 W closing power and holds at 0.27 W, making it suitable for control circuits where a DC holding coil is not required. Contact reliability is specified for PLC-level signals (17 V, 5 mA), so it can switch low-energy loads like a programmable controller input without needing a separate interface relay.
Side-by-side mounting is permitted with no derating gap required.
Screw-type terminals on both the main current circuit and the auxiliary/control circuit. Accepts 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) finely stranded with ferrule.
Protection and coordination
For type of coordination 2 (limited damage under short circuit), use a gL/gG NH 3NA fuse rated 20 A; for type of coordination 1 (no damage to the contactor), a 35 A fuse of the same type is required.
