Transparent rectangular overload relay with screw terminals

Schneider Electric

Schneider Electric LRD06 Overload Relay 1 A – 1.6 A 690 V

SKU CH-KEF3-EDVQC

Protects three-phase circuits with a 1 A to 1.6 A thermal overload relay rated for 690 V

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Protects motors from overload with 1 A to 1.6 A thermal trip range
  • Handles up to 690 V AC for industrial power circuits
  • Trip class 10A gives fast response to sustained overcurrent
  • Manual reset lets you confirm fault clearance before restart
  • Direct contactor mounting with screw-clamp terminals simplifies installation

Purpose and user

This Schneider Electric LRD06 overload relay protects three-phase motor circuits by monitoring current between 1 A and 1.6 A. It suits maintenance engineers and panel builders who need IEC‑style thermal protection for motors rated up to 690 V AC.

Installation context

The unit mounts directly onto a compatible TeSys Deca contactor using screw‑clamp terminals, so no separate DIN‑rail space or extra wiring is required. Its manual reset and 1NO/1NC auxiliary contacts free up panel area while giving clear trip indication and control‑circuit interlocking.

Upgrade scope

The relay replaces older thermal overloads that lack the 10A trip class or the 690 V rating, and it supersedes units with fixed current settings. The step up is worthwhile when an application demands adjustable protection from 1 A to 1.6 A in a compact, contactor‑mounted package.

Highlights

  • Protects motors from overload with 1 A to 1.6 A thermal trip range
  • Handles up to 690 V AC for industrial power circuits
  • Trip class 10A gives fast response to sustained overcurrent
  • Manual reset lets you confirm fault clearance before restart
  • Direct contactor mounting with screw-clamp terminals simplifies installation

Questions about this item

At what current does the thermal overload trip under sustained load?

The relay trips when current exceeds the 1.6 A maximum setting, using a Trip Class 10A thermal curve.

How much heat or noise does the unit produce during continuous operation?

As a passive thermal relay it generates no audible noise and only minimal heat from the screw-clamp terminals carrying up to 1.6 A.

Which contactor series must I already own for direct mounting?

It mounts directly onto Schneider Electric TeSys Deca contactors using the integrated screw-clamp terminals.
