Application:
The product is a Type 2 low-voltage surge protective device (SPD). It is designed for installation at the boundaries of subsequent protection zones (e.g., LPZ1-2, LPZ2-3) within low-voltage distribution systems. This device protects sensitive equipment by safely discharging the remnant surge currents and transient overvoltages resulting from indirect lightning effects or switching operations.
