Rated switching current reaches 10 A at 24 V, derating to 6 A at 230 V and 3 A at 400 V, covering typical control-circuit voltages across 50/60 Hz systems. Fastening method allows both screw fixing and snap-on mounting to a DIN rail. Size S00 keeps the footprint compact at 45 mm width and 57.5 mm height. ## Electrical Ratings and Contact Performance Mechanical endurance is listed at 30,000,000 operating cycles typical. Shock resistance is 10g / 5 ms and 5g / 10 ms, ensuring reliability under vibration. The contactor is rated for both 50 Hz and 60 Hz operation, with frequency-dependent switching current ranges of 0.8...1.1 at 50 Hz and 0.85...1.1 at 60 Hz.","metaTitle":"Siemens 3RH1140-1AK60 SIRIUS Auxiliary Contactor, Size S00,","metaDescription":"Siemens 3RH1140-1AK60 SIRIUS auxiliary contactor, size S00, 4 NO contacts.
