Product Description
Application:
Mainly used for home and similar use of low-voltage distribution lines, when the line over voltage or undervoltage failure can automatically disconnect, and can automatically detect the line voltage, when the line back to normal when the automatic closure.
Products with high-speed low-power processing as the core control, high load capacity Magnetic holding relay for the main control circuit,
with online production voltage LED digital display, indicator light status indication, the product can be sustained under high pressure shock.
Timely protection of the safe use of load appliances. Product protection action when the neutral line is not open, in the installation should be consistent with GB16895.21 and other relevant installation procedures.
Features:
1. When the line undervoltage occurs in time to cut off the line, the line voltage back to normal when the delay automatically connected to the line, without human operation.
2. Line transient overvoltage or voltage sag and short interrupt, the protector does not move, to ensure reliable operation of the line.
3. Protector itself has a high voltage withstand capacity, line fault voltage continues to 440V, the protector can safely protect the function itself will not be damaged.
