Siemens SIRIUS 3RT Size S2, 3RT2 Contactor, 24 V ac/dc Coil, 3-Pole, 40 A, 18.5 kW, 3NO, 400 V ac

Bring your low-voltage circuits to life with this contactor from Siemens. It controls the opening and closing of your electrical feed, so automatically ensures devices are powered when needed. A built-in varistor provides over-voltage protection by clamping down on transient surges. As the unit is insulated, you can handle it safely without risking an electric shock. A typical mechanical service life of up to 10 million cycles means it keeps up with even the fastest applications. Choose a contactor like this to switch current to the electric motors or load feeders found in industrial power supplies and lighting systems.
