Lightning protection for power system Class 4

 Application range: 380D/220D series are applied to equipotential bonding of the main low voltage distribution boxes in the building, providing protection against the overvoltage arising from the lightning strike to power supply system of class 4 or faulty operation.( option from standard IEC61643- 1 and Gb50343)

Main structure and work principle.

Plug& Play design, live-wire replacement, easy maintenance.

Build-in temperature control and circuit breaking technology, high security performance 

Green light in notice window indicates normal, red indicates broken, replacement notice, which are clear and easy distinguished.

Optional telesignalisation monitoring interface, realizable remote monitoring.

Function of lightning protection backup half of protection ability is avaliable while either red light on

Assembled 1P+N 2P 3P+N 4P etc pattern. applied for various electric network system

Invalid disengage device

When the protector is overheated and invalid arising from the aging or breakdown, the build-in invalid disengage device can automatically break away fromthe electric network , meanwhile reporting failure signal. The indicator is light off while in regular work, will turn into red after invalid and disengagement. Normal for light off Replace for any red light on
