4、 Function and Features

1. It has protection against overload, phase failure, locked rotor, three-phase imbalance, etc.
2. It has overcurrent inverse time delay function. Therefore, the optimal operating time can be calculated based on the multiple of motor overcurrent.
3. It has a starting delay function, which is separated from the delay time of overcurrent operation.
4. It has the function of a digital ammeter, so it can display the actual working current and set the protection value at the rated current of the motor.
5. Equipped with fault memory current digital display function.

6. Easy to install, interchangeable with JR16, JR36 and other thermal relays, and can be installed on the card rail.
