Din SPD (BK Series)
Din Surge Protective Device

The BK Series AC/DIN type surge protect protects a 50/60Hz electric system from surge voltages. The system also allows replacement of the protective element (MOV), ensuring convenience and economy. However, as only the protective module is provided, other components should be added when the system is installed according to the site condition. When the protective device is activated (in an anomaly or an accident), the red lever in the status indicator protrudes.
