Siemens SIRIUS 3RT Size S0, 3RT2 Contactor, 24 V ac Coil, 3-Pole, 16 A, 7.5 kW, 3NO, 400 V ac

Need a safe way to turn high-power equipment on and off? Switch to this 3-pole contactor from Siemens. It uses a low-voltage 24V coil to operate a circuit carrying up to 400V AC, so you're not in direct contact with dangerous levels of electricity. Handy screw terminals make the unit quick to install and you get connections that can tolerate vibration. Thanks to a low power loss of 0.6W per pole, you can be sure this is an energy-efficient choice for use with electric motor starters and in lighting control systems.

• 6kV impulse voltage rating means it can handle overvoltage with ease
• Wide operating temperature range between -25°C and +60°C so it's reliable in challenging conditions
• Compact dimensions of 45 (W) x 97 (D) x 85mm (L) to fit into busy setups

The poles on this contactor are in a 3NO configuration, meaning they're open in their normal state and current can't pass through the circuit. When the 24V coil is energised, it closes the contacts and your device powers up.
