- 機能 & アプリケーション
コア機能
過負荷保護: Realizes inverse-time protection via the thermal bending of bimetallic strips.
Short-circuit Protection: Achieves instantaneous protection through electromagnetic release.
残留電流保護: Rapidly trips within ≤0.3s when detected residual current exceeds 30mA, preventing electric shock accidents.
典型的なアプリケーションシナリオ
- Branch circuit protection for residential/commercial buildings (例えば, lighting and socket circuits)
- Electrical safety protection for crowded places such as offices and shops
- Power supply protection for small household appliances and office equipment
- Replacement for traditional MCB + RCCB combinations, 配電ボックスのスペースを節約する
選択のヒント
AC-type is suitable for pure AC load environments, such as traditional lighting and resistive loads.
For loads containing DC components (例えば, スイッチング電源, LED照明), A-type or B-type residual current circuit breakers are recommended.
30mA is the standard value for personal safety protection and shall not be used for equipment protection (300mA is usually selected for equipment protection).
- インストール & メンテナンスのポイント
- 配線仕様: トップインボトムアウト (bidirectional wiring with bottom-in top-out supported). Connect phase line to L pole and neutral line to N pole; 逆接続は厳禁です.
- Residual Current Test: インストール後, テストボタンを押してください (T button) to confirm the normal operation of the residual current protection function.
- 定期点検: Press the test button once a quarter to verify the effectiveness of the residual current protection function.
- 障害処理:
Overload/Short-circuit Tripping: Troubleshoot load or line faults before closing the breaker directly.
Residual Current Tripping: First disconnect all loads, check for leakage points one by one, and close the breaker only after repairs; forced closing with faults is strictly prohibited.
- Spacing Requirement: Maintain a gap of ≥3mm from adjacent components to ensure heat dissipation and wiring space.
