The product features and functions

This protector technology has reached the international advanced level of the same kind, the main features of the direct strike lightning protection, not need to install decoupling inductors, it can solve the problem that the secondary protector cannot be installed at the same time because there is not enough space. Datong flow rate and ultra-low voltage protection level, reasonable modular design, which can realize V-type wiring mode, its active energy matching technology prolongs the service life of all parts of the product. This protector makes use of C-level voltage limiting device to reflect the characteristics of fast limiting voltage and low voltage, restrain the surge voltage at a certain level during the initial period of the surge, at the same time, the electronic ignition device of the trigger circuit collects the transient pulse overvoltage to carry out the boost to reach the B level main electrode and the ignition voltage. Releasing most of the surge energy, at the same time, C class limit the overvoltage, reach the low voltage protection level, the switch device and the current period of energy perfect combination, which can protect the electrical equipment very well.

Installation and application

JZDY-B C series active energy matching surge protector is suitable for single and three-phase distribution system with AC 50HZ (60HZ), rated working voltage 220 / 380V in signal phase, three phase system. It can be widely used in power supply environment of lightning sensitive buildings and factories, especially suitable for the condition that the self-inspection of grade I II surge protector which cannot meet the installation distance of 10 meters conductor, such as base station, monitoring system. Response Speed and low Voltage Protection level of Class II surge Protector. Product installation of low voltage distribution system entry line for LPZOA or LPZOB area junction. The surrounding environment should be less exposed, without significant shock and impact. The two ends of the product should be as short as possible, if conditions permit, Kevin wiring should be used.
