Selection of Type LR\bK Overload Relays
These overload relays are designed for the protection of motors. They are ambient-compensated and
phase-failure sensitive. They may be reset either manually or automatically.
For direct mounting, the relays are placed under the contactors with screw clamp terminals only
(pre-wired terminals; see page 64). For separate mounting, use terminal block LA7K0064 (see below).
The front face of the overload relay provides:
• Selection of reset mode: Manual (marked H) or Automatic (marked A).
• A red pushbutton for the Trip Test function.
• A blue pushbutton for Stop and manual reset.
• A yellow trip flag to indicate that the overload relay tripped.
