Siemens 3RT1 Contactor, 127V Coil, 3-Pole, 265 A, 132 kW 127V, 2 NO/2 NC, 1kV

When you want to make or break, switch circuits on and off safely with this contactor from Siemens. It's designed to work with three-phase motors up to 132kW and is rated for resistive loads, transformers and squirrel-cage rotors, as well as discharge and incandescent lamps. This makes it suitable for use with building infrastructure and industrial control machinery. The contactor has a varistor suppressor to protect your circuit from high-voltage spikes, increasing the safety of your operations. It comes with auxiliary contacts in a 2NO and 2NC configuration to let you carry out secondary switching functions. The versatile design means you can combine multiple contactor modules and mount switches (such as 210-3322) on the front to boost your machine controls.

• Screw terminals for reliable wire connections that won't wobble loose

Thanks to a mechanical service life of 10 million switching cycles, you can be sure the contactor is durable and long-lasting.
