IntroductionSP5 series surge protection devices are suitable for all levels of lightning protection areas under AC 50/60Hz, 230/400V TT, IT, TN-S, TN-C, TN-CS and other power supply systems, and can discharge up to 100KA lightning overcurrent.Installation should be installed as close as possible to the upstream line end of the protected equipment, and connect the outer conductor (L) or neutral line (N) to the grounding device of the customer's equipment. If the installation distance cannot be guaranteed, additional installations are required between all levels of protectors. Decoupling components, adding an inductor in low-voltage power supply system can achieve the purpose of decoupling.Product Features- New designed cases;
- Low residual voltage of impulse current, high withstand capacity;
- Fast response time less than 25ms;
- Stable integrated base, modular design with hot-plug;
- Indication window color shows SPD status; (Green for normal, red for fault)
- 35mm Rail mounting, match most general installation requirements.
