Scope of application 

Applicable to single-phase current and voltage 220V, frequency 50Hz, rated current 63A and below the user or load. As a neutral line fault caused by single-phase line under-voltage on the single-phase power equipment protection

It is mainly used for the voltage protection of distribution lines in the household box or in the single-phase / three-phase power equipment.

Model and meaning 

The main technical parameters 


Product Features 

○ Single-phase line over-voltage occurs is cut off the circuit, single-line line voltage returned to normal by the delay after the automatic reset connected to the line, without manual operation.

○ Line transient or transient overvoltage, the protector does not produce malfunction.

○ line due to the contact is not real, such as failure of voltage instability or sudden power failure and a sudden call, the protector is not connected to the line.

○ When the line fault voltage is the highest, the protector itself will not be damaged.

○ protector in inverse time action characteristics, action time ≤ 1s.

○ Voltage protection range: 0 ~ 450V.

○ withstand impulse voltage: 4kv (load Class III electrical safety standards).

○ Protector has red, green light-emitting diodes indicate the working state, green - normal voltage indication, red - delay or fault indication.

○ Modular design, rail-mounted.

○ Wiring: 25 mm2 and below insulated wire.
