Auxiliary Contact Modules

Overview

Auxiliary contact modules give an indication of the contactor status. It is used for remote visual signaling, alarming, electrical interlocking, and relay activation as required. The auxiliary contact terminals use screw technology.

There are two types of auxiliary contact modules depending on the contact arrangement:

• 1 NO + 1 NC contacts: LAG8N11 and LAG8N11P with different terminal identification. Each contactor is shipped with one LAG8N11P mounted on the contactor right side.

• 2 NO contacts: LAG8N20 and LAG8N20P with different terminal identification.

The NC auxiliary contacts are mirror of the main pole contact according to IEC 60947–4–1 annexure F. The NO and NC auxiliary contacts are mechanically linked according to IEC 60947-5-1 / EN 60947-5-1 annexure L.

Up to four auxiliary contact modules can be mounted on one contactor. All combinations of the auxiliary contact modules are possible with maximum 2 on each side.
