Contactor relay

Contactors are divided into power contactors and auxiliary contactors. The eibabo catalog offers a wide range of auxiliary contactors and contactor relays for all applications. Typical uses of contactor relays are control purposes and the automation of switching processes. Auxiliary contactors are, unlike power contactors, mostly designed for switching currents of up to 6A. Among the auxiliary contactors are, among others, time relays and safety relays for electrical installations. When the switch of the auxiliary contactor is operated electromechanically, a control current flows through a magnetic coil and the resulting magnetic field draws the contacts into the active switching position. When the current no longer flows, the initial state is restored due to the built-in return spring. Contactors and auxiliary contactors operate similar to a relay, but are designed for higher switching capacities. An auxiliary contactor relay is not different from a conventional low-power relay, but its design is similar to that of a normal contactor. If the auxiliary contactor relay is used together with another contactor or power contactor, the term 'auxiliary contactor' is used. This indicates that the auxiliary contactor does not switch power but merely assumes switching functions and control functions. Many auxiliary contactors are usually 4-pole in their basic version and can be extended by means of a combination with auxiliary switch blocks to several poles (eg 8 poles). Many contactor relays are designed for both AC operation and for DC operation. When choosing your required contactor make sure that the chosen contactor is suitable for the function. Our shop provides a wide selection of high-quality relays and contactor relays: auxiliary contactors are available with screw connection or spring terminals and, depending on the type, are suitable either for mounting on a top hat rail / DIN rail or screw mounting. The auxiliary contactor relays have standardized connection designations and help you to save time and money through an optimized and effective connection system.
