Install the Level 3 surge protection device inside the equipment or at the equipment's power supply input, especially for critical or sensitive electronic devices. Technical Requirements Maximum discharge capacity: 20kA per phase or lower. Voltage protection level: ≤ 1800V. Installation compliance, correct bonding, grounding, and short leads are critical to prevent equipment damage. Internal transients and inadequate coordination often cause surge protection failures. Technical Specifications for Lightning Protection of Electronic Information Systems in Buildings (GB 50343-2012) 5. According to the principle of graded lightning protection, and based on the likelihood of a building being struck by lightning, it is necessary to. Among other things, standardized requirements for line lengths, effective protection areas and fuse protection of surge protection devices must be observed. This prevents interference from being coupled.
