- Core Functions and Working Principle
- Surge Suppression Mechanism: Adopts MOV+GDT hybrid technology. MOV is responsible for fast response (≤25ns) to suppress most surges, while GDT provides higher surge withstand capacity and lower leakage current.
- Fault Indication Function: The pluggable module is equipped with a visual status indicator (緑色 = 通常, 赤 = 故障) for quick identification of protection status.
- サーマルトリップ保護: Built-in thermal trip device automatically trips when surge energy is excessive or components age, preventing overheating damage to the arrester.
- Replaceable Design: Only the pluggable trip module needs to be replaced after a fault, eliminating the need for overall replacement and reducing maintenance costs.

- 設置および操作上の注意事項
- 設置場所:
As Type 2 保護, it should be installed in the main or distribution power cabinet, after the main circuit breaker.
Recommended to be installed close to the protected equipment, with the line length not exceeding 10 メートル.
- 配線要件:
Phase lines (L1/L2/L3) and neutral line (N) must be wired correctly according to the markings.
The protective earthing (PE) wire should be as short and thick as possible. It is recommended to use ≥16mm² copper conductors with a length not exceeding 50cm.
All terminals must be tightened to the recommended torque (8～10N・m) to prevent overheating due to poor contact.
- Matching Requirements:
A 16A~32A miniature circuit breaker or fuse must be installed upstream as overcurrent protection to prevent short circuits caused by surge arrester faults.
Not applicable to IT and TN-C earthing systems, only suitable for TN-S and TT systems.
- メンテナンスポイント:
Regularly check the status indicator (緑色 = 通常, 赤 = 故障).
Replace the pluggable trip module in a timely manner after a fault; do not perform plug-in operations with power on.
It is recommended to conduct a surge protection performance test every 2 年.
