Siemens 3RT2035-1AV60 Industrial Three Phase Contactor

Siemens 3RT2035-1AV60 is a three‑pole S2 power contactor in the SIRIUS 3RT2 family, rated for AC‑3 duty at 40 A and up to 18.5 kW at 400 V. It features a main circuit with screw terminals and an integrated auxiliary contact block offering 1 normally open and 1 normally closed contact. The coil is 480 V AC at 60 Hz, enabling direct control from standard 480 V control circuits, while the device provides insulation up to 690 V for the main circuit and a maximum permissible voltage of 400 V between the coil and main contacts per EN 60947-1. The enclosure carries front IP20 protection and IP00 for the terminals. For reliability, it lists shock resistance of 11.8 g / 5 ms (rectangular impulse) and 7.4 g / 10 ms, with a mechanical life of up to 10 million switching cycles in typical use. The compact S2 frame with screw terminals suits industrial panel applications and supports an operating range from -25 to +60 C, up to 2,000 m above sea level, and up to 95% relative humidity at 55 C. Commonly used as a motor starter in three‑phase automation, the 3RT2035-1AV60 is appropriate for controlling loads such as conveyors, pumps, and fans in manufacturing or process environments.
