Lightning Protection Breaker SPD LD-B22E3, LD-B22E3S

basic information

*Features* 1. Integration of SPD external isolator (MCCB) and SPD, resulting in the shortest internal wiring. By integrating the SPD external isolator, the external wiring between the SPD and the isolator becomes zero, significantly reducing wiring labor. By keeping the wiring as short as possible, optimal lightning protection can be achieved. 2. Inspection function with disconnector that allows inspection while the main breaker is energized. Wiring breaker (MCCB): During the replacement or inspection of the SPD section, the circuit can be opened by operating the breaker, allowing work to be done without voltage. 3. High protection capability. Voltage protection level is below 1300V, impulse current Iimp 25kA, protecting facilities and equipment from damage caused by direct lightning strikes. 4. SPD section can be replaced independently. 5. Excellent responsiveness and no continuous current. Response speed: less than 3nsec. 6. Safety features even during degradation. - Two-stage protection function (automatic disconnection device inside the SPD operates, and the SPD external isolator trips). - SPD function display included. - Degradation contact output compatible (only for LD-B22E3S). 7. Compliant with RoHS regulations.
