Minimum clearances: 10 mm upwards, downwards, and forwards; 6 mm at the sides. Those numbers govern how tightly you can nest contactors in a multi-row enclosure without compromising arc quenching or heat dissipation. ## Duty and switching frequency This contactor is rated for different switching frequencies depending on the duty category. At AC-1 (resistive loads) it manages up to 1,000 operating cycles per hour. For AC-3 (squirrel-cage motor starting) and AC-3e the maximum is 750 cycles/h. AC-4 (plugging / inching) drops to 250 cycles/h. The arcing time sits between 10 and 15 ms at AC, and the make / break duration is 4 to 15 ms — both figures matter when coordinating with upstream short-circuit protection for selectivity. The auxiliary switch is present on this variant. Its rated current at 24 V is 10 A, at 48 V and 60 V it is 2 A, and at 110 V it is 1 A. At 230 V the auxiliary is rated 1 hp. These ratings define what pilot devices or PLC outputs the auxiliary can switch directly without an interposing relay. The magnet coil terminates at screw-type terminals. Main contacts accept solid or stranded conductors from 0.5 to 4 mm², and the terminals can take two conductors per clamp: 2×(0.5…1.5 mm²), 2×(0.75…2.5 mm²), or 2×4 mm². That dual-conductor capacity simplifies daisy-chaining the line side without extra junction blocks. The typical mechanical life of the contactor is 30 million operations.","metaTitle":"Siemens SIRIUS 3RT2016-1AT61 Power Contactor, 45 mm, Screw T","metaDescription":"Siemens SIRIUS 3RT2016-1AT61 power contactor, size S00, 45 mm width, screw terminals.
