Schneider Electric LRD02 Overload Relay

The Schneider Electric LRD02 is a thermal overload relay designed for three-phase motor protection in industrial control panels. It suits electricians and maintenance engineers who need reliable overload detection for small motors operating within a 0.16 to 0.25 ampere current range. The transparent housing allows visual inspection of the internal mechanism and contact status. It mounts directly onto compatible TeSys Deca contactors for a compact assembly.

Sustained load behaviour and trip response

Rated for Trip Class 10A, the relay trips within a defined time under persistent overcurrent conditions rather than momentary surges. The thermal element responds to prolonged heating caused by sustained overloads, protecting motor windings from gradual damage. The maximum voltage rating of 690V AC supports standard industrial supply networks. Auto and manual reset modes give operators flexibility to restore operation after a trip event once the fault is cleared.

Installation and common issues

Direct mounting onto the contactor eliminates separate DIN rail hardware and reduces wiring time. Screw clamp terminals accept solid or stranded conductors and must be torqued correctly to prevent loosening under vibration. A common issue is selecting a relay with a current range that does not match the motor full-load amperage, leading to nuisance tripping or failed protection. The 1NO/1NC auxiliary contacts integrate into control circuits for remote signalling or interlocking.

Questions about this item

Does the LRD02 generate noticeable heat or noise when running continuously at 0.25 A?

The relay is a thermal overload device with no moving parts or fan, so it operates silently and its heat output is limited to the normal dissipation of a 0.16–0.25 A current path.

What contactor or mounting hardware must I already have to install this overload relay?

It mounts directly to a TeSys Deca contactor using screw-clamp terminals, so a compatible Deca contactor is required for installation.

Will the Class 10A trip curve of the LRD02 coordinate with older Class 10 thermal relays on the same 690 V AC circuit?

Yes, both are Class 10/10A devices with the same 690 V AC rating, so their trip characteristics align for coordinated protection.
