Auxiliary Contactors

Auxiliary Contactors

Contactors are usually classified in load contactors/breakers (contactors with high switching capacity) and auxiliary contactors. So, what is the difference between a "regular" contactor and an auxiliary contactor?

Auxiliary Contactors

The load contactor usually is used as the main contactor. It handles loads of about 600 A / AC1. Auxiliary contactors, on the other hand, are designed for switching currents of only up to 6 A. Among the auxiliary contactors count e.g. timer relays and safety relays. Basically, an auxiliary contactor is a regular (low-power) relay - but built like a "regular" contactor and when used together with another contactor it is called auxiliary contactor to clarify that it is not used for switching loads but has an activation/deactivation or control function instead - used to connect/disconnect a circuit (in a nutshell: to control load contactors). Therefore, auxiliary contactors usually only have auxiliary contacts and no main contacts.

 

Schrack Technik offers auxiliary contactors with 4 pins; available for electronic applications or for high switching capacity.
