Contactor Relays

Contactors are generally used for loads with high voltages and/or currents, in devices over 15A and 3kW, while Contactor Relays are the electrical switching devices used for low voltage control and auxiliary electrical circuits. Their primary function is controlling the current to an electric motor or other type of load, but they also provide signals and can be used to interlock switchgear panels and switching devices.

A Contactor Relay is used to open and close the contacts so as to cause other devices to operate, either in the same or an associated circuit, and draws much less power that the Contactor itself. It is effectively the intermediary between an electronic circuit and a Contactor. The electronic circuit turns on the relay, which then switches on the larger voltage source required to turn on the Contactor.

The basic type of Contactor Relay is designed with 4 poles, but expanded 8 pole versions are also available with permanently mounted auxiliary switch blocks. Contactor Relays are supplied with screw-type or spring-type terminals. They can be used in any climate and have several different contact configurations, which allows them to be combined with many other low voltage control products.

At Rowse Automation we can supply a wide range of Contactor Relays for all kinds of application, varying in size, number of contacts, current type and voltage, from 24V AC or DC Coil to 110V, 220V and 230V AC Coil versions.
