Circuit breakers and fuse boxes are the safety shield of electrical installations. They automatically disconnect the circuit in dangerous situations such as overcurrent, short circuit and ground fault, preventing fire and electric shock risks.
Circuit Breaker Types
- Type B: Suitable for lighting circuits and resistive loads. Instantaneous trip at 3-5 times nominal current.
- Type C: The most common type for general purpose use. Ideal for motor loads and socket circuits. Trip at 5-10 times nominal current.
- Type D: Designed for industrial motors and transformers with high starting current. Trip at 10-20 times nominal current.
Residual Current Devices (RCD/RCCB)
- 30mA Sensitivity: For human protection, mandatory in residential and commercial buildings.
- 300mA Sensitivity: For fire protection, used in industrial facilities.
- Combined RCBO: Compact solutions combining both overcurrent and residual current protection.
Fuse Box Selection Criteria
Key factors include module count (with 20-30% extra capacity recommended), mounting type (surface or flush), IP protection class, and material choice.
Safety Tips
Always choose TSE and CE certified products, use separate circuit breakers for each circuit, test RCD monthly, and keep the fuse box door closed at all times.
