The main load for AC 50Hz/60Hz, rated voltage 400V-690V, rated current to 120A and below a three-phase asynchronous motor in general, no special requirements may appear under the condition of operation of the off phase, serial, blocking, blocking and unbalance fault protection. The utility model has the advantages of strong anti-interference ability, stable and reliable work, high precision, simple and convenient installation and debugging, etc..

Functional characteristics:

1, perfect protection function: as the protector is arranged inside the cold and hot overload protection characteristics of K coefficient curve detection circuit and unbalance detection circuit, so it can be on the motor starting may appear in the running process of the phase failure, overload, blocking, blocking and unbalance fault using inverse time characteristic to solve the protection, motor overload, while starting block does not protect the problem.

2, high reliability with cold starting delay time is long, the characteristics of thermal overload quick action, can satisfy the normal load, no special requirements under the condition of operation of the motor; because detection protector broken, overcurrent detection link independent of each other, so whether it is light load and heavy load, open phase whether it is overload, when starting or running, the motor overload phase interruption, in the whole process of the work can be a reliable protection.

3, clear state instructions: protector with current calibration instructions, the implementation of the knob linear quantization, adjust the current, the user as long as the motor according to the rated current value can be adjusted, the operation is simple and convenient. With normal operating instructions and action protection after the failure of the state memory instructions. During normal operation, operation indicator light, as the protector of internal delay circuit according to the integral coefficient of K curves, running lights with the load current size for different frequency flicker when the motor overload protector, overload protection action, indicator light, when the fault phase or three-phase current unbalance fault when the phase interruption protector action, indicator light, protection under different fault protection action, the corresponding fault indicator lights and lock, conveniently determine fault.

4, scientific control: because the auxiliary contact output interface protector GT200-J for two independent sets of normal open auxiliary contact form, 95, 96 closed protection output device is power protection, protection tripping protection, output 95 and 96 auxiliary contacts in the off state. The alarm output auxiliary contacts 97 and 98 are closed. If the protector itself fails, the output auxiliary contacts 95, 96, 97 and 98 are disconnected, so the control method is more rational.

5 、 installation wiring is simple and convenient: in order to meet the needs of different users installation, each shell rack level adopts different installation methods, through type fixing and rail installation. The high current adopts the cable once through mutual inductor, and it can be completely isolated from the main circuit. It is suitable for different voltage levels.

6, thermal power protection device on memory: when the motor is running the heat accumulation and heat decay were maintained after stopping dynamic tracking, over-current protection action memory; after the reset time and hot state memory is proportional to the solution to the motor protector can not adapt to the frequent changes of motor load occasions.
