S00 frame, 45 mm width — panel fit
The 3RT2018-4AN61: This is a Size S00 contactor, 45 mm wide and 73 mm deep, with a height of 58 mm.
Switching capacity across voltages
Rated operational current varies by voltage and duty: at 480 V the contactor switches 14 A; at 400 V it handles 3 A; at 230 V it is rated for 2 hp. The magnet coil connection uses a ring cable lug — confirm the lug ring size against the coil terminal stud before wiring.
Duty-cycle limits and mechanical endurance
Maximum operating cycles per hour: 1,000 in AC-1 (resistive), 750 in AC-3 (motor start/run), and 250 in AC-4 (plugging/inching). The typical mechanical life is 30 million cycles — the electrical life will be lower and depends on the switched load and duty class.
