Schneider Electric TeSys LRD thermal overload relay, catalogue LRD22, for motor overload and phase-loss protection when paired with a compatible TeSys contactor. The relay monitors motor current and trips the control circuit during sustained overload conditions. It is intended for conventional motor starters and direct-on-line applications. The adjustable current range is selected to suit the protected motor. Correct contactor coordination and setting must follow Schneider tables. Reset/trip characteristics depend on the exact variant. Key specifications: Family TeSys LRD; device type thermal overload relay; application motor protection; current range variant-specific; protection overload/phase loss; contactor coordination TeSys D where specified.
