20kA Surge Protective Device

20kA surge protective device

Price:2-8 USD

Description:

HDU1-II20X series surge protector device(hereinafter referred to as SPD) is used for power supply system such as IT,TT,TN-C,TN-S,TN-CS, etc. for low-voltage AC distribution system, for indirect lightning and direct lightning or other A surge of transient overvoltage is protected. The SPD has a common mode(MC)protection. The SPD complies with GB/T18802.1/IEC61643-II.

Installation:

Installed at the junction of LPZ1 or LPZ2 and LPZ3, 35mm standard rail is installed, and the multi-strand wire connecting enamel is 2.5-16mm2.

The SPD must be protected at each pole-using a fuse or miniature circuit breaker or a dedicated backup protector.

Applicable to household distribution boxes, computer equipment, information equipment. Electronic equipment and control equipment in front of or in the nearest outlet box.

Main structure and working principle:

SPD is a port, anti-stock protection, indoor fixed installation, voltage limited type.

SPD built-in disconnector. When the SPD fails due to overheating and breakdown, the disconnector can automatically detach its grid and given an indication signal. When the SPD is woking normally, the visible window displays green, and when the failure is detached, it displays red.

1P+N,2P+N,3P+N consists of 1P, 2P,3P SPD+NPE zero ground protection module, applied to TT, TN-S and other power supply systems.

Main Character:

1.3 phase protection for TN-S,TT and other systems

2.It is easy for installation and maintenance by pluggable module

3.Quick response and high discharge capacity

4.Our SPD provides more reliable protection by Double thermal disconnection devices.

5. When fault, green window will change and also provides remote alarm control.
