Auxiliary Contact Modules

Auxiliary contacts give an indication of the contactor status. They can be used for remote visual signaling, alarming, electrical locking, relay activation, and others. Each contactor is equipped with 1 NO (normally open) and 1 NC (normally closed)

auxiliary contact block as standard. Mechanically linked mirror contacts

The NC (normally closed) contact of the auxiliary contact block is a mirror contact in conformity to IEC 60947–5–1. It is mechanically linked to reliably represent the state of the main power contacts and wherever auxiliary contact state reliability is essential. The NC contact of the auxiliary contact cannot be closed at the same time as a normally open power contact. Contact module compatibility TeSys™ Giga auxiliary contact module is compatible with a range of TeSys Giga contactors. Each TeSys Giga contactor can be equipped with up to four auxiliary contact modules.
