(1) WHPTC the power input to do with lightning protection lightning protection components , overcurrent protection Applications: In this application , mainly to avoid supply voltage fluctuations , lightning current interference generated overcurrent damage related equipment.
 

(2) WHPTC in a single multi- branch power supply system in the application: In this application, able to solve a single piece of equipment damage due to make the whole system crash issue. WHPTC in this system can be solved because one of the devices ( such as building intercom in a single user ) short-circuit of the entire system can not work the problem , to achieve the ultimate goal is when the short circuit appears to be timely protection fault isolate the device from the system without affecting the normal operation of other equipment . Can effectively avoid the installation is easy to produce a variety of errors ( such as short circuit, power lines reversed , data cable and power lines are wrong ) , and damage to equipment.
 

( 3 ) solve the over-temperature protection issues : the outdoor equipment, faulty equipment due to heat and high current exceeds the normal operating temperature , WHPTC can be provided promptly after the device over-temperature protection.
