Series Overview
Series Overview
- LR97D, solid - state overload relay, can compare the motor current with the currently preset current.
- The D - Time down counter starts counting only during the motor starting process. If the stable operating current of the motor exceeds the overload current setting value, LR97D will close the contact after O - Time. The delay times for phase failure and rotor lock - up are 3 seconds and 0.5 seconds respectively.
- As a safety pin (mechanical shock) protection, turning the O - Time knob to the minimum value can make it trip within 0.2 - 0.3 seconds.

- Installed on TeSys contactors
