Product Overview

According to the GB/T18802.1-2011 standard, the front end of the SPD circuit must be connected in series with the overcurrent protection appliance required by the surge protector manufacturer. Because the current fuses and miniature circuit breakers cannot be coordinated with SPD, when the power supply is abnormal or the SPD is deteriorated and fails, the fire and equipment damage caused by lightning strikes have seriously affected the normal production and operation！
At present, the miniature circuit breakers used with SPD masters cannot be matched with the following 4 points.1. The lightning current impact is very easy to damage. The lightning protection fails, 2. The lightning surge current residual voltage is high. The reliability of the lightning protection of the equipment is reduced； 3. Power frequency continuous current does not trip, a power supply abnormal SPD fires； 4. Lightning shock accidentally trips and lightning protection fails.

Functions and scope of application

The SPD special external detach is connected in series on the SPD return path, and the internal current separation channel device is used to achieve a low-current speed cut with high current and lightning shock. To achieve the protection of small power current SPD fire protection, lightning impact SPD continuous protection role, SCB products limit the use of thousands of SPD back pass current protection, or backup current protection should not be used in other occasions.
