TXZD1-63 Residual Current Circuit Breaker has all the features of existing leakage protection switch / air switch and the "auto recloser circuit breaker" function of introduced large-scale professional equipment, performance and reliability is also greatly improved. This auto recloser Circuit Breaker has leakage protection, low voltage protection, over-voltage protection, over-current protection, short circuit protection, short circuit before closing detection, automatic reclosing, delay start, regulation and monitoring dry node output. Applicable to AC 50Hz or 60Hz rated voltage bipolar 220V / 230V, rated current up to 32A line environment. When the electrical equipment leakage, overload, short circuit, human and animal electric shock occurs, can automatically cut off the power automatically after the failure to eliminate automatic circuit recloser transmission, without manual closing to ensure the normal use of electrical equipment.
Single-phase auto recloser Circuit Breaker can solve the problems caused by lightning lightning, socket flashover caused by transient faults can not automatically restore power supply after the power failure, but also through the real-time monitoring of power supply line voltage, current, leakage and other operating conditions On the electrical equipment and line for the sub-gate protection.
Single-phase auto recloser Circuit Breaker uses high-voltage automatic recloser controller technology, to achieve strong isolation, effective isolation, to prevent mutual interference and surge intrusion, reduce false action, prolong product life and improve product stability and reliability . The use of traditional mechanical switches and single-chip micro-electronics combination of design concepts, to retain the traditional mechanical switch safe and reliable and intelligent electronic products sensitive to the characteristics of the installation and maintenance personnel to ensure the safe use of electrical equipment and effective.

It is suitable for the protection of line and power equipment overload, short circuit, leakage, over voltage, under voltage, automatic power off etc. protection and auto reclosing function. The auto recloser Circuit Breaker is suitable for AC 50Hz and rated current up to 63A. Can be widely used in a variety of environments unattended equipment, electricity protection or electrical fire safety requirements of high occasions, such as mobile communication base stations, PHS base stations, satellite ground receiving stations, microwave stations, program-controlled switches, network switches Communication system, communication switches, signal amplifiers, electronic monitoring, cable TV amplifiers, environmental monitoring stations, weather telemetry stations, energy pipeline telemetry stations, and places requiring high safety and fire protection.

TXZD1 single-phase automatic circuit recloser can automatically reclosing after tripping, with zero line of fire protection and zero line disconnection protection, uninterrupted protection of equipment, unattended equipment to ensure continuous work and reduce losses.
1) Intelligent leakage identification: Identify all kinds of interference signals and leakage signals, to avoid false leakage trip.
2) Automatic power off: the line power, automatically disconnect the input and output lines. Re-call, the power supply is detected properly, then automatically power on.
3) zero FireWire connected to the protection: This function in the zero line of fire when the anti-closing, to avoid the occurrence of electrical burnout
4) zero line disconnection protection: When the "zero line" loose or be cut, resulting in voltage imbalance, this function in the voltage imbalance, the automatic power supply disconnected.
5) remote control: internal with RS232 communication interface, if necessary, external, convenient and remote monitoring equipment connected to achieve remote monitoring.
6) fault alarm: the protection disconnect at the same time, different red light, indicating the corresponding fault type.
7) Safety and stability: the use of mechanical switching characteristics and automatic recloser controller technology, protection products stable and reliable, very low failure rate.
8) Compensated regulated output: 90% efficiency,

There are five indicators on the board of automatic reclosing electric protector, from left to right are operation, voltage, leakage, short circuit, output.
