Three-phase four-wire overvoltage and under-voltage current limiting protectors are currently available in the market.
A new generation of home appliance protection devices developed by the Electric Condition Institute. Control circuit selection
Assembled with imported components, produced using modular standards for performance
Excellent and reliable. Capable of being positive under abnormal voltage, current, and phase sequence conditions Work regularly. When the mains voltage and current exceed the action threshold of the protector
When the phase sequence is disordered and the voltage and current are unbalanced, the protector can quickly Reliably cut off the circuit to protect electrical equipment and personal safety.
When the mains voltage returns to normal, the protector can automatically connect to the power supply
Restore power supply, automatic implementation of local functions, no need for personnel operation.
Main functions:
1. Overvoltage protection, under-voltage protection, overload protection, undercurrent protection, delay protection Time protection, voltage imbalance protection, current imbalance protection, shortage Phase protection, and phase sequence protection, each parameter can be set with an action threshold and on/off.
2. The backlight display shows no action for 180 seconds, and the relay is disconnected with a red backlight, Normal white backlight
Installation and usage conditions:
1. Temperature: -20℃~60
2. Humidity: ≤85%
3. Altitude: not exceeding 2000m
4. Pollution level: Level 3
5. Modular design for exterior design and guide rail installation.
6. Wiring capacity: Insulated copper wire of 35 square millimeters and below.
