Product introduction
KW - D20 series surge protector (surge protector) applied to ac 50 hz / 60 hz, 380 v, TN and TN under - S - C - S, TT, IT, such as power supply system, can be used as LPZ1, LPZ2 and LPZ3 bonding interface, and the design basis in accordance with GB18802.1, iec61643-1, installed on the 35 mm electric guide shell design, the product for failure from the device. When the surge protector is overheated; When the breakdown occurs, the failure disengagement device automatically disallows the device from the grid, while the visual warning indicator module can be replaced with a working voltage.
Product features
Replace the protector unit without a power failure.
The maximum can withstand 20KA (8/20 mu s).
The action response time is less than 25 nanoseconds.
4, the visual window color indicates the protection work state, green (normal), red (faults).
The electronic information system is a necessary product for lightning protection.
Product application and installation location
Apply to D lightning protection, KW series - D20 surge protector accord with GB18802.1-2002, when used in lightning equipotential connection, installed on LPZ1, LPZ2 area with LPZ3 area border, are normally installed in resident distribution box, computer center, information equipment, electronic equipment and control equipment before or recent socket in the box.
Product design and order information: 1, the user should specify the model number and quantity in detail when designing and ordering the product. For example: kw-d20/4p-385,8.
