  • Product colorDark Gray
  • Front-mount design simplifies panel wiring
  • Two normally-open contacts expand control circuits
  • 10 A AC rating handles standard industrial loads
  • 690 V AC maximum voltage suits high-voltage panels
  • Screw-clamp terminals ensure secure connections

Purpose and Fit

The Schneider Electric LADN20 is an auxiliary contact block designed for industrial control circuits. It adds two normally open contacts to compatible TeSys, TeSys Deca and TeSys F contactors. The block is rated for 10 A at up to 690 V AC and mounts on the front of the host device.

Compatibility Check

Verify that the existing contactor belongs to the TeSys, TeSys Deca or TeSys F series before ordering. Confirm the control circuit voltage does not exceed 690 V AC and that the application requires only normally open contacts. Ensure a front-mounting slot is available on the contactor for this accessory.

Build and Daily Use

The dark grey housing carries an IP20 rating for finger-safe protection in panel environments. Screw clamp terminals accept solid or stranded conductors for secure wiring. Front mounting allows the block to be added or removed without disassembling the contactor, simplifying maintenance and circuit changes.
