The mechanical life of 10,000,000 operations gives a baseline for maintenance intervals — the electrical life will be lower under heavy AC-4 duty and should be derated per the manufacturer's curve. ## Mounting and Integration — DIN Rail Fit This Size S2 contactor measures 55 mm wide by 112 mm tall by 115 mm deep, fitting a standard 35 mm DIN rail (DIN EN 50022). The screw and snap-on fastening method lets you clip it onto the rail without tools, then secure with screws for vibration resistance. The IP20 protection on the front and IP00 at the terminals means it belongs inside a cabinet, not exposed to washdown.","metaTitle":"Siemens 3RT1035-1AB00-1AA0 SIRIUS Power Contactor, 24 VAC Co","metaDescription":"Siemens 3RT1035-1AB00-1AA0 SIRIUS power contactor, 24 V 50 Hz coil, Size S2.
