three-phase four wire overvoltage and
undervoltage current limiting protector is currently available
in the market
A new generation of home appliance protection device
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, undervoltage 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 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.

Precautions: |
1. This product has no isolation function. Please disconnect
the front stage when repairing the circuit
Circuit breaker switch.
2. The zero line (N line) of this product is directly connected
without disconnection function.
3. The protector must be wired according to the markings
and must not be connected incorrectly.
4. Although this product has limited current protection
function, it cannot replace circuit breakers,
Please install circuit breakers such as DZ47 and C65 at the
front end of the line
Short circuit protection.
5. Before use, please tighten the clamp screw to prevent
poor contact and
