Applications
　　The composite power system surge protection device, integrated with two-level protection of B-level and C-level, is suitable for LPZ0A-LPZ2 lightning protection zones interface and it is installed in the main distribution system. Installation of a set of products to achieve primary and secondary power surge protection without the use of decoupling inductors, it is especially suitable for the situation that there can not meet the requirement of *0 meters mounting distance between two protection levels.

　　B+C composite power surge protection device is specifically designed for level I (class B) and level II (class C) surge protection in low-voltage power supply system. The product has features of small in size, large surge discharge capacity, low voltage protection level and fast response. It removes the installation of decoupling device between level I and level n surge protection devices and restriction of connection wire length between two levels, it is especially suitable for the situation that there can not meet the requirement of *0 meters mounting distance between lightning arrestor (CLASS I ) and surge protection device (CLASS II), it saves installation space, simplifies installation technology and optimizes the wire connections.


Features
♦ High energy absorption capacity (*0kA, *0/**0μs), low output residual voltage, quick response.
♦ Active energy control that ensures energy compatibility of level-I and level-II modules.
♦ Provide integrated protection that enjoys the SPD advantages of both level-I and level-II.
♦ Modularization and standard *5mm rail installation that are convenient for installation and maintenance.
♦ The module with deterioration indication function can be added with remote signaling alarm.
