Schneider Electric LRD365L Overload Relay 48-65A

The Schneider Electric LRD365L is a three-pole thermal overload relay designed for motor protection in industrial control panels. It suits electricians and maintenance engineers who need reliable overload detection for three-phase circuits up to 690 V AC. The device mounts directly onto compatible TeSys Deca contactors using screw clamp terminals for secure wiring.

Class 20 trip with single-phase sensitivity

This relay replaces basic overload devices that lack single-phase sensitivity or adjustable current ranges. The jump is worth it when motors require protection against phase-loss conditions and nuisance tripping must be minimised during heavy starting duties. The adjustable dial covers 48 A to 65 A, matching the full-load current of the protected motor.

Sustained thermal protection under load

Under continuous operation the thermal element models motor heating and trips at Class 20 timing when the set current is exceeded. Auto and manual reset modes allow quick restart or supervised recovery after a fault event. The 1NO/1NC auxiliary contact provides remote status signalling to a PLC or indicator light without additional accessories.

Questions about this item

What contactor series does the LRD365L mount directly onto?

The overload relay mounts directly onto the TeSys Deca contactor series using its built-in screw clamp terminals.

Which reset modes are available on the LRD365L after a trip?

The relay offers both automatic and manual reset; a common mistake is leaving it in auto mode when a manual restart is required for safety.

What auxiliary contact configuration does the LRD365L provide for signalling?

It includes one normally open and one normally closed auxiliary contact (1NO/1NC) for trip indication and control circuits.
