● Realizes selective control and tripping mechanism breaking through current parameter variation;
● Low residual voltage under impulse current, with test performance superior to circuit breakers and fuses;
● Adopts high-energy materials to solve the service life issue of the product;
● The product can be used with three types of SPD: T1, T2 and T3;
● Mounted on 35mm DIN rail for use;
● Remote control alarm is optional;
● LYSCB surge backup protector is a specially developed product that provides backup protection solutions for SPD. It eliminates the potential safety hazards when using circuit breakers or fuses as SPD backup protection.
● LYSCB is suitable for TT, TN and other power supply systems of 50/60Hz and below 400V. It features no false tripping when lightning current passes through, rapid current cut-off in case of SPD breakdown and short circuit, and low residual voltage under impulse current. The product complies with GB18802.1-2011, IEC61643-11-2011 and other standards.
