The mechanical service life is typical 30 million operations, meaning it will outlast most equipment it controls in a normal cycling application. Switching frequency limits depend on duty: 1 000 cycles/hour for resistive loads (AC-1), 750 cycles/hour for motor starting (AC-2, AC-3, AC-3e), and 250 cycles/hour for plugging or inching (AC-4). This matters when the contactor is used in a frequent-start conveyor or a jogging station — AC-4 duty cuts the allowable rate by three-quarters. The magnet coil uses screw-type terminals, so wiring is straightforward with a standard screwdriver. Size S00 contactors like this one are the go-to for small motor control in industrial panels — think pump starters, small conveyor drives, fan controls, and valve actuators in manufacturing lines, HVAC plant rooms, and water treatment skids. The 45 mm width leaves room for other components on a crowded DIN rail. ## Integration notes Conductor cross-sections accepted range from 0.5 to 4 mm² for solid or stranded wire, with twin-wire terminations possible up to 2×4 mm².","metaTitle":"Siemens 3RT2018-1AB01-ZW97 SIRIUS Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT2018-1AB01-ZW97 power contactor, Size S00, 45 mm width, 73 mm depth.
