Product Details

New 3P 10~100kA SPD new electrical surge protection device (SPD)

Product Description

Application

The products comply with IEC61643-1, GB18802.1.

The housing is fixed on 35mm electrical guide, and with failure release device inside. As long as SPD become invalid after the breakdown caused by over-heat and overload current, the failure release device will be disengaged from power system automatically with the warning indicator turning from Green (normal) to Red (failure).

SPD is usually installed in household power distribution boards, telecom machinery center, computer equipment center, elevator control center, hospital's surgery and ICU, information equipment, electronic equipment and in front of control equipment or nearest socket box of control equipment.

Special Tips

1.it is modularization design and can be replaced without cutting off power.

2.maximum current endurance by lightning stroke is 10KA

3. response time less than 25ns.

4.with warning indicator: Green (normal); Red (failure).

5. high-tech, powerful energy, gap discharge pole (N-PE).

6.Built-in over current and over thermal pertection,temperature control and circuit breaking technology.

7.Excellent ZnO voltage dependent resistor slice with owned intellectual property.

8.Little leakage current,rapid reponse,low residual voltage.

9.Equipped with remote signaling interface,it can realize remote control .

Transient over-voltages due to direct lightning effects
