TeSys integral auxiliary contact — 2 NO + 1 NC

Part of the Schneider TeSys range, this is an auxiliary contact block designed for integral starters and contactors in the TeSys family. It mounts on the left side of the contactor or starter assembly. The contact configuration is 2 normally-open plus 1 normally-closed, with instantaneous operation — no time delay. This suits signal feedback and interlocking in motor starter circuits.

Electrical ratings and terminal details

These define the maximum voltage and continuous current the contact block can handle in a control circuit. Termination is via screw clamp terminals accepting 1.5 mm² (one terminal) and 2.5 mm² (two terminals) conductors — standard for control wiring in panel builds.

Frequently asked questions

What is the closest alternative to LA1LC021 in the TeSys range?

No official successor or pin-compatible alternative is recorded for this obsolete part. A functional replacement would require checking the current TeSys auxiliary contact range for a 2 NO + 1 NC block with left-side mounting and 690 V insulation rating.
