Motor protectorIt provides comprehensive protection for the motor, and provides protection measures when the motor has overcurrent, undercurrent, phase failure, stall, short circuit, overvoltage, undervoltage, leakage, and three-phase imbalance. It has start-up delay, digital ammeter and voltmeter functions, can display A, B, C three-phase running current, realizes multiple parameter setting functions, fault memory alarm query and action value holding functions, and call self-start and automatic reset functions.

SelectionMotor protectorThe purpose of the device is to enable the motor to fully exert its overload capacity while avoiding damage. It can also improve the reliability of the electric traction system and the continuity of production. At the same time, when selecting a protection device, several conflicting factors must be considered, namely reliability, economy, simple structure, and easy operation and maintenance. When the protection requirements can be met, a simple protection device should be considered first. Only when a simple protection device cannot meet the requirements or when higher requirements are placed on the protection characteristics, a complex protection device should be considered.

Due to the continuous development of insulation technology, the design of motors requires both increased output and reduced size, making the thermal capacity of new motors smaller and smaller, and the overload capacity weaker and weaker; and due to the improvement of production automation, motors are required to run frequently in various modes such as frequent starting, braking, forward and reverse rotation, and variable load, which puts higher requirements on motor protection devices. In addition, motors are more widely used and often work in extremely harsh environments, such as humid, high temperature, dusty, corrosive, etc. Coupled with the irregularities in motor repair and equipment management, all of these have caused today's motors to be more easily damaged than in the past.
