General                                                                               
         The Modular Power Supply SPD is made from special non-metallic materials by using the stack discharge technology. It is used in primary power distribution systems to protect installations against direct lightning strikes and induced surges.
Features                                                                             
         High discharge capacity, low residual voltage, and high follow current extinguishing capability.
         Standard guide rail installation.
         Failure indication and remote signalling alarm interface for faults.
Standards Complied
