Specifications

Product Description:
This product is designed to protect low voltage devices from surge damages, mainly used in power supply system such as power distribution-room, distribution-cabinet and other important power supply system. Widely used to protect mobile communication station, telecommunication centre, airport, finance, and so on..
 
 
Main character:
※     High discharge capacity, quick response
※     Low voltage protection level and with double terminals for parallel or series (V-shape) Connection
※     Multi functional connection for conductor and busbars
※     Window will display red when fault occur, also provide remote alarm terminal at the same time
