A275-25KH-1P/2P/3P/4P

It is suitable for the low-voltage side of the transformer or LPZ 0-LPZ 1 zone with a rated frequency of 50/60Hz and a rated working voltage of 230/400 V. It is suitable for Class I lightning strikes or surge overvoltages of the power supply (especially the power line introduced by the overhead line). Protect. This product is not suitable for systems where the expected short-circuit current is greater than the rated disconnection freewheeling value. A fuse should be connected in series with the front end of the product.
