Lightning protection for power system Class 1

380A-A/4
Application range
380A-A/4 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 the power supply system of class I or faulty （operation option from standard IEC61643 1 and GB50343）
Main structure and work principle.
☆ Build-in temperature control and circuit breaking technology, high security performance. ☆ Light-off in notice window indicates normal, red indicates broken, which are clear and easy distinguished. ☆ Function of lightning protection backup, the protection ability is avaliable without red light on. ☆ Optional telesignalisation monitoring interface, realizable remote monitoring. ☆ Realizable Kevin wiring, to reduce conductor resistance. ☆ 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 fromthe 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
