Product Description
CGB300 intelligent microcomputer motor protector is a new generation of intelligent integrated device integrating monitoring, protection, alarm and control. In addition to advanced protection, alarm and monitoring functions, the protector also provides important information such as fault trip records and rated parameters, and uses a field bus structure, which brings great convenience to intelligent control and management. It is suitable for the main circuit AC 40~65Hz, voltage to 660V circuit, and the circuit breaker and contactor in the AC motor circuit. It is widely used in electric power, petrochemical, light industry, coal, paper industry, iron and steel, metallurgy, textile and other industries.
With overload protection, locked rotor protection, three-phase current imbalance protection, phase failure protection, underload protection, ground leakage protection, starting overtime protection, overvoltage protection, undervoltage protection, phase sequence protection and other comprehensive protection.
Fault warning function.
Remote communication: RS485 communication (Modbus RTU protocol), baud rate, communication address and data format can be set.
4 ~ 20mA analog output.
Remote fault reset and fault record save function.
LCD liquid crystal display, friendly man-machine interface.
Using high-performance industrial microprocessor, high integration, strong function and fast speed.
The accuracy of the measured three-phase current value, voltage value, zero sequence current value and analog output is within ± 1%.
The action value, action time error and set value error of each protection function are within ± 2%.
All parameter settings are not lost after power failure.
Strong anti-interference ability.
