ELCB stands for Earth Leakage Circuit Breaker. It’s a safety device designed to protect people from electrical shock by:
1. Detecting earth leakage currents
2. Tripping the circuit when a fault is detected
1. Sensitivity (e.g., 15mA, 30mA, 100mA)
2. Tripping time (e.g., 10ms, 50ms)
3. Rated current (e.g., 16A, 32A, 63A)
1. Monitors current flow to earth
2. Detects leakage currents
3. Trips the circuit when a fault is detected
4. Disconnects power supply
1. Voltage-independent ELCB
2. Voltage-dependent ELCB
3. Active ELCB
4. Passive ELCB
1. Residential and commercial buildings
2. Industrial power distribution
3. Hospitals and healthcare facilities
4. Swimming pools and bathrooms
5. Outdoor installations
1. Enhanced electrical safety
2. Protection against electrical shock
3. Reduced risk of fire
4. Compliance with safety standards
5. Easy installation and maintenance
ELCBs are essential safety devices, providing protection against earth fault currents and ensuring a safe electrical environment.
Note: ELCBs are often replaced by RCCBs (Residual Current Circuit Breakers), which offer similar functionality with additional features.
