KXBY1 Surge protection device Moulded case installed on 35mm standard electric rail, inside this product have failure release unit,

KXBY1-B surge protective device series:

Application:KXBY1-B series surge protective device apply to TT,IT,TN-S,TN-C,TH-C-S etc electric supply system with AC50/60Hz,voltage less than 230V/400V, according to criteria: GB18802.1,GB50057, maximum can release 60-150kA thunderstrike over current, normally install into structure incoming wire low voltage main distribution box. Discharge energy into earth rapidly once thunderstrike caused overvoltage or operation over voltage, makes electric grid after over voltage impact still can lower than the specific maximum over voltage, prevent electric apparatus impact by thunderstrike overvoltage or operation overvoltage.

Model No. and meaning:

KXBY1-B surge protective device series

Product feature:

1. Modularization: No need cut off power supply when replace protection unit

2. Discharge electric current: Maximum can bear 60-150Ka(8/20us)

3. Swift: Operate action time less than 20ns
