Product Description

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, over-voltage, over current occurred in the power system due 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 needed again, it can be mounted on 35mm railway, compared with normal combination of fuse + SPD module, there has following advantages:
  1. Residual voltage reduce more than 50%, for normal combination, fuse body and connected conductor have inductance, and 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.
  2. Easy installation, saving space, saving installation cost in cabinet.
  3. Quickly response speed, comprehensives performance being improved.
  4. Better N point: no matter which step of circuit, there has shortest distance for discharge surge current, residual voltage decrease more.
  5. In order to prevent the surge protector failure after the impact of power grid security, each pole must be connected in series with a front-end surge protector LY-SCB back-up protection.
