The coil voltage is 110 V at 50 Hz — that's a standard control voltage in many European and Asian industrial panels, so if your control transformer is wound for 110 VAC, this contactor drops straight in without an interposing relay. At 110 V the auxiliary contacts carry 1 A; at 440 V they're rated 1 A; at 690 V they drop to 1 A — the current derating above 400 V is modest, so the contacts handle control circuits on 690 V systems without a problem. ## Mechanical life and switching duty For a motor starter cycling once per minute on a conveyor, that's about 19 years of continuous service before the mechanism wears out. ## Clearance and side-by-side mounting Side-by-side mounting is allowed — you can gang multiple S2 contactors without a gap.","metaTitle":"Siemens 3RT2535-1AF00 SIRIUS Contactor, 110 V 50 Hz Coil","metaDescription":"Siemens SIRIUS contactor 3RT2535-1AF00, size S2, 110 V 50 Hz coil, screw terminals.
