Product introduction
In order to meet with user demand, we developed new generation LYD1-R series protector with built-in circuit breaking device, to limit surge current, overvoltage, over-current occurred in the power system duo to some reasons, working in the system of AC 50Hz, rated voltage 380V and below to prevent surge voltage from damaging electric equipment.
Features:
LYD1-R series protector has integrated short circuit protective function in its SPD module fuse not need again, it can be mounted on 35mm railway, compared with normal combination of fuse SPD module, there has following advantages.
Residual voltage reduce more than 50%, for normal combination, fuse body and connected conductor have inductance, and it will result in residual voltage, but LYD1-R series almost has no residual voltage at this case, therefore it can get better result of protecting equipment.
Easy installation, saving space, saving installation cost in cabinet.
Quick response speed, comprehensive performance being improved.
Better N point: no matter which step of circuit, there has shortest distance for discharging surge current, residual voltage decrease more.
