    Motor protection relay, Current detection relay

    Do You Face These Problems?

    1. Alarms do not occur before equipment is damaged.

    2. Protection is necessary because of poor power supply quality

         overseas.

    3. The motor is often burnt out for default phase, which produces high maintenance cost.

    4.The crane motor is often burnt out for overload, which interrupts the production plan and takes too much time to disassemble and assemble.

    5. The frequently started compressor and the short-circuit contactor cause default phase or phase imbalance which leads to shutdown of the equipment and thus affecting the delivery time.

    6. The water pump often idles and drily turns which cause burnout of the motor, bringing many complaints about the quality of the pump from customers.

    7. The equipment goes wrong at midnight and then works properly when you are about to test the problem, making it hard to find out the cause and completely solve the problem.

    8. When using the motor protector or the thermal overload relay made by another manufacturer, the motor is still burnt out because of its slow response and ineffective for protection.

    9. It’s hard to select correct protectors for too many different sizes of motors, while short of the specific motor you need because of limited inventory, resulting into unduly used resources. This also annoys installers who have to take too much time looking for the corresponding size and model.

    10. The motor starts with high current which may lead to false operation of the protector.
