Product Description
The NDU3-35 switch modular high-performance SPD is based on IEC standard design, with high lightning flow capacity, suitable for lightning high-risk areas of the first level of lightning protection power supply system
"Products using modular design, good sealing, standard 35 off electrical rail installation, wiring is very convenient, simple maintenance and so on. The products are widely used in microwave communication station 7 station. Telecom room, industrial factories and mines. Financial. Securities and other power systems. Important and vulnerable to lightning.""Flow capacity of large, fast response Residual pressure is very low, no continued flow Pluggable structure with LED degradation indicator" "Flow capacity is large, fast response Residual pressure is very low, no continued flow"
