- Functions & Applications
Core Functions
과부하 보호: Realizes inverse-time protection via the thermal bending of bimetallic strips.
Short-circuit Protection: Achieves instantaneous protection through electromagnetic release.
Residual Current Protection: Rapidly trips within ≤0.3s when detected residual current exceeds 30mA, preventing electric shock accidents.
일반적인 애플리케이션 시나리오
- Branch circuit protection for residential/commercial buildings (예를 들어, 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, saving distribution box space
Selection Tips
AC-type is suitable for pure AC load environments, such as traditional lighting and resistive loads.
For loads containing DC components (예를 들어, 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).
- Installation & 유지관리 핵심 사항
- Wiring Specifications: Top-in bottom-out (bidirectional wiring with bottom-in top-out supported). Connect phase line to L pole and neutral line to N pole; reverse connection is strictly prohibited.
- Residual Current Test: After installation, press the test button (T button) to confirm the normal operation of the residual current protection function.
- Regular Inspection: Press the test button once a quarter to verify the effectiveness of the residual current protection function.
- Fault Handling:
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.
