Design and Performance
Differential Protection Against Phase Failure and Unbalance
As a differential thermal overload relay, the LRD12 detects overcurrents in the motor supply lines alongside phase failure and load unbalance, disconnecting power via the connected contactor to minimize damage to motor windings when a fault occurs.
Flexible Manual or Automatic Reset with Trip Indicator
Compensated relay design with a manual or automatic reset selector and a relay trip indicator gives operators clear, immediate visibility into fault status, supporting fast troubleshooting and recovery after an overload event.
Compact, Direct Contactor Integration
Combined with TeSys D contactors in a compact 45 mm wide space (up to 38 A), the LRD12 forms an extremely compact motor starter assembly without requiring additional mounting hardware or wiring.
Compatible with Fuse or Circuit-Breaker Protection Schemes
Designed for use with fuses or magnetic circuit breakers (GV2L and GV3L series), the LRD12 supports flexible short-circuit protection coordination alongside its own overload protection function.
Multiple Terminal Options for Installation Flexibility
Available with screw clamp, spring terminal, ring terminal, or EverLink terminal connections, the LRD series lets engineers match the overload relay’s termination style to their specific wiring standards and installation preferences.
