Design and Performance
Differential Protection Against Phase Failure and Unbalance
As a differential thermal overload relay, the LRD08 detects both overload conditions and phase failure/load unbalance, providing more comprehensive motor protection than a standard bimetallic overload relay.
Flexible Manual or Automatic Reset
An integrated manual-automatic reset selector, combined with a test selector for simulating a trip, reset and stop buttons, and a visual flag indicator, gives operators flexible, straightforward control over overload response and troubleshooting.
Compact, Space-Saving Contactor Integration
Designed to combine directly with TeSys D contactors (LC1D09 through LC1D38) in a compact 45mm wide space, the LRD08 forms an extremely compact motor starter assembly without requiring additional mounting hardware.
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.
Reliable Class 10A Trip Response
A Class 10A tripping characteristic conforming to IEC 60947-4-1 provides fast, standards-compliant response to overload conditions, helping protect connected motors from damage during sustained overcurrent events.
