Isolated Power & Network Surge Protector SH-SPD101PW
Feature
- Maximum Discharge Current: 10KA or 20KA (8/20μS), dual-stage composite protection for power lines.
- Balanced & Safe Circuit Design: Full-mode protection for both differential mode (line-to-line) and common mode (line-to-ground) with low residual voltage. Ideal for outdoor equipment requiring strict residual voltage limits under high lightning energy.
- Dual-Stage Series Composite Protection for Network Lines: Comprehensive differential/common mode protection with low residual voltage and extended service life.
- Network Interference Isolation: Filters out clutter, enhances signal transmission rates, and is particularly suitable for long-distance signal transmission.
- Potential Difference Protection: Prevents equipment damage caused by sudden voltage increases between power and network lines.
- Compact & Integrated Design: Space-saving form factor.
- LED Status Indicator for Power Surge Protection**: Green (normal operation); Off (failure).

Product Detail
Description
The SH-SPD101PW Power & Network Dual-Function Surge Protector, Power & Network Combined Surge Arrester, or Power & Network Integrated Surge Protective Device, the SH-SPD101PW is designed in compliance with IEC and GB standards. It is primarily used to protect low-voltage equipment, security devices, telecommunications equipment, and network devices against lightning electromagnetic pulse (LEMP) on power supply and 100M network signal lines. This all-in-one multifunctional surge protective device (SPD) offers comprehensive protection for critical systems.
Installation Instructions
- This surge protective device (SPD) shall be installed in series ahead of the protected equipment’s port (“INPUT” terminal connected to the incoming line, “OUTPUT” terminal connected to the protected equipment). The “PE” terminal must be connected to the lightning protection ground network or equipotential terminal strip.
- Power Line Terminal Connection (Power Supply Part): Connect the two ends of the power supply to “L/+” and “N/-” respectively.
- RJ45 Network Signal Line Connection: Install in series; directly plug the RJ45 crystal head into the corresponding port.
- The cross-sectional area of the grounding wire shall be ≥2.5mm² and as short as possible. The grounding resistance for installing this surge protector shall be less than 4 ohms, ensuring optimal lightning protection performance when the grounding wire and resistance meet the requirements.
- This surge protector requires no maintenance, but its operating status shall be promptly inspected and recorded after thunderstorms.

Notice
- All ports on the surge protector’s output side must be connected to the protected equipment.
- Do not reverse or misconnect positive/negative lines, and never perform live operations.
- The surge protector should be installed as close as possible to the front end of the protected equipment for optimal effectiveness.
- Regularly inspect the equipment. If the product deteriorates, replace it immediately.
- Grounding must be reliable, with a grounding resistance of ≤4Ω. For high-difficulty grounding environments (e.g., mountainous areas or sandy soil), the resistance may be relaxed to ≤10Ω.
