Product Details

Product Introduction

GC-XB200 protector is suitable for voltages below AC660V; The low-voltage system with current ranging from AC5A to 800A adopts advanced design concepts and manufacturing processes, combined with the needs of domestic users for low-voltage circuit protection, measurement, and control, to develop low-voltage line protectors suitable for domestic users.

This protector provides a complete set of specialized solutions for low-voltage circuits, integrating control, protection, measurement, metering, and communication. It also offers functions such as remote automatic control, on-site direct control, panel indication, signal alarm, operation record, trip alarm record, and switch quantity record. It is widely used in many industries such as power, petrochemical, light industry, coal, paper, steel, metallurgy, etc.

Product Features

Rich measurement data, including phase voltage, line voltage, phase current, current phase angle, total active power, total reactive power, total apparent power, power factor, forward and reverse active/reactive energy, total active/reactive energy, etc;
Equipped with residual current protection function, it can provide more sensitive ground fault detection, fully ensuring safe operation and personal safety in low-voltage circuits;
Up to 9 active or passive switch inputs are provided for the connection of opening and closing signals, circuit breaker status signals, contactor status signals, and fault signals;
Equipped with AO output function, it can easily convert the measured quantities (three-phase voltage, three-phase current, power, power factor, frequency) in the low-voltage circuit into 4-20mA DC current, achieving the function of a conventional fully isolated transmitter;
Having the management and maintenance function of low-voltage circuits, recording the opening and closing time, frequency, and cumulative tripping times;
Equipped with SOE function, it can record up to the last 100 protection action information with time stamps;
Support optional Profibus DP protocol communication interface;
Equipped with remote communication function, supporting optional 2-channel RS-485 communication interface, using standard Modbus RTU communication protocol; Easy maintenance and management, displaying fault parameters, alarm information, status indicators, circuit breaker opening and closing times, tripping times, etc., facilitating fault analysis, production efficiency statistics, and selective and reasonable maintenance.
