Application:
This product is a high-capacity, low-voltage surge protective device (SPD) designed for Type 1 (Class B) installation at the main power inlet of low-voltage distribution systems, located at the boundary between LPZ0 and LPZ1 zones. It protects sensitive electrical equipment against damage from direct lightning strikes and induced transient overvoltages.
