Schneider Electric LRD332L Overload Relay

This Schneider Electric LRD332L overload relay provides thermal protection for three-phase circuits. It handles a current range of 23 A to 32 A with a maximum voltage rating of 690 V AC. The unit mounts directly to a compatible contactor and features screw clamp terminals for secure wiring. It is designed for industrial electrical control and automation applications.

Compatibility and Installation Checks

Verify that the contactor series is TeSys Deca to ensure direct mounting compatibility. Confirm the motor full-load current falls within the 23 A to 32 A adjustment range before ordering. Ensure the control circuit can accommodate the 1NO/1NC auxiliary contact configuration for signalling. Check that the Trip Class 20 characteristic matches the required motor starting time.

Build Quality and Daily Use

The transparent housing allows visual inspection of the relay status during operation. Direct contactor mounting reduces panel space and simplifies installation without separate DIN rail hardware. Screw clamp terminals accept solid or stranded conductors for reliable connections in vibration-prone environments. Auto and manual reset options give flexibility for restoring operation after a thermal trip event.

Questions about this item

What accessories or cables are included with the LRD332L overload relay, and what must be purchased separately?

The relay ships as a single unit with screw-clamp terminals ready for wiring; no cables, connectors or mounting hardware are included, so supply your own control wiring and a compatible TeSys Deca contactor for direct mounting.

How do I decide between the 23 A minimum and 32 A maximum current settings on this relay?

Set the dial between 23 A and 32 A to match the motor’s full-load current; choose the lowest setting that still exceeds that current so the trip class 20 thermal protection operates correctly.

What does the 690 V AC rating mean when the relay is installed in a three-phase panel?

It is the maximum phase-to-phase voltage the relay’s main poles can switch; the 32 A / trip class 20 thermal unit protects three-phase loads up to that voltage when mounted directly on a TeSys Deca contactor.
