Schneider Electric LR2D3559 Overload Relay

The Schneider Electric LR2D3559 is a thermal overload relay designed to protect three-phase motors in industrial control panels. It mounts directly to a TeSys Deca contactor and offers an adjustable current range from 48 A to 65 A. The unit provides both automatic and manual reset options for operational flexibility.

Suited for motor starters needing IEC-style

This relay fits panels using screw-clamp wiring and a 1000 V AC maximum rating. It is not suitable for applications requiring a NEMA-sized overload block or a trip class other than Class 20. Installers needing a different current band or plug-in terminal style should select another model.

Adjustable 48-65 A thermal trip range

The single specification that determines fit is the adjustable thermal trip window of 48 A minimum to 65 A maximum. This range must match the motor full-load current exactly; a motor drawing less than 48 A or more than 65 A cannot be protected by this device.

Highlights

  • Thermal protection for 48–65 A circuits
  • Trip Class 20 prevents nuisance tripping
  • Auto or manual reset restores operation fast

Questions about this item

How do I verify the LR2D3559 overload relay is working correctly after wiring it to a TeSys Deca contactor?

After installation, confirm the relay trips when current exceeds the 48–65 A setting range and that the 1NO/1NC auxiliary contacts change state; the Trip Class 20 timing and Auto/Manual reset function should operate as expected.

What accessories are included with the LR2D3559 and what must I purchase separately for a complete installation?

The relay itself is supplied with screw-clamp terminals for direct contactor mounting; you will need to source the TeSys Deca contactor, power wiring, and any required DIN-rail or panel hardware separately.

Which current setting should I select on the LR2D3559 for a motor drawing 55 A full-load current?

Set the adjustment dial within the 48 A minimum to 65 A maximum range so that 55 A falls comfortably inside the band, ensuring Class 20 thermal protection at up to 1000 V AC.
