product description

Intelligent motor protection is comprehensive motor protection, motor over-current, overload, idling, phase loss, stall, short circuit, overvoltage, undervoltage protection measures to be leakage and three-phase imbalance, the main application control and protection for fans, pumps, motors and other loads.

Protection integrated motor pumps full range of protection technology, micro-processing chip as the core of the arithmetic unit, the operation speed, high reliability, and has a complete communications and analog transmitter output capability. Motor to provide better protection aspects of the comprehensive, reliable, easy to operate, but easy to install and maintain. The scope and sensitivity than the high thermal relay, can effectively avoid the motor burned out, thermal relay action is not the case, the thermal relay is ideal upgrade products.

RC15-40 motor (pump) intelligent protection, for 50HZ.380V phase AC motor circuit, overload, idling, over-voltage Fault of a new protector.

Scope

In everyday use, causing the motor burned main reasons are the following:

◎ contact with a contact due to arc impact wear, resulting in motor phase.

◎ submersible pumps, sewage pump due to water extraction was complete, the cooling water pump in a short time and not get burned.

◎ water pump for a long time do not rust stuck or gravel stuck impeller and burned.

◎ due to internal motor bearing wear caused by stuck stall.

◎ long motor overload burned.

◎ due to overload or under-heating of the motor and cause burn.

These are the main causes of the motor burned, RC15-40 series intelligent protection in modern industry motor burnout, play a significant protective effect, making it easy to bring production units.
