Function

The Siemens 3RT2037-1AN60 Power Contactor is primarily used for switching electric motors and resistive loads. It functions as an electrically controlled switch, allowing a low-power signal (from the 200 V AC coil) to control a high-power main circuit (up to 65 A / 30 kW). It is a core component in motor starters (Direct-on-line, Reversing, or Star-Delta) and can be easily combined with a range of accessories, such as overload relays and auxiliary switch blocks, for complete load feeder solutions.
