Measuring 457 x 457 x 203 mm and weighing less than 30.4 kg, the Jennings RP173 series of three-phase vacuum contactors is built tough to work in a variety of heavy-duty applications. Able to withstand the frequent switching required to control furnaces and large motors, this contactor can also be used to switch power transformers and capacitor banks for voltage regulation and power factor correction as a means of reducing operating costs.

The RP173 series is ideal for use in motor controllers that operate production and processing equipment, mining and petroleum equipment, earth movers and conveyors, power shovels and all types of industrial loads.

Using a trio of Jennings vacuum interrupters, the three-phase unit provides a short contact-to-contact gap required to interrupt the circuit for highly reliable operation. The contact materials are rated for 7.2 kV, 600 A load life and 6,000 A fault current.
