- Funzioni & Applicazioni
Funzioni principali
Protezione da sovraccarico: Realizes inverse-time protection via the thermal bending of bimetallic strips.
Protezione da cortocircuito: Achieves instantaneous protection through electromagnetic release.
Residual Current Protection: Rapidly trips within ≤0.3s when detected residual current exceeds 30mA, preventing electric shock accidents.
Scenari applicativi tipici
- Branch circuit protection for residential/commercial buildings (per esempio., 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, risparmio di spazio nella scatola di distribuzione
Suggerimenti per la selezione
AC-type is suitable for pure AC load environments, such as traditional lighting and resistive loads.
For loads containing DC components (per esempio., switching power supplies, LED lighting), 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).
- Installazione & Punti chiave della manutenzione
- Specifiche di cablaggio: Top-in bottom-out (bidirectional wiring with bottom-in top-out supported). Connect phase line to L pole and neutral line to N pole; il collegamento inverso è severamente vietato.
- Residual Current Test: Dopo l'installazione, premere il pulsante di prova (T button) to confirm the normal operation of the residual current protection function.
- Ispezione regolare: Press the test button once a quarter to verify the effectiveness of the residual current protection function.
- Gestione dei guasti:
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.

Key Replacement Precautions
- ✅ Installation Compatibility: Both are mounted on 35mm DIN rails with 18mm width, enabling direct interchange.
- ✅ Protection Characteristics: C-type curve, 16Una corrente nominale, and 30mA residual current protection are fully consistent; no load adjustment is required.
- ⚠️ Wiring Adaptation: Schneider terminals support larger wire diameters; keep the original wire diameter during replacement to avoid loose connections.
- ⚠️ Function Identification: The VisiTrip indication window of Schneider shows red after tripping; it is necessary to train operators to recognize the new marks.
