🔹MCB
• Protects against overload and short circuit
• Used in homes and small commercial wiring
🔹RCCB
• Protects against earth leakage / electricshock
• Does not protect from overload or short circuit
🔹 Wi-Fi Breaker
• Controlled through mobile app / internet
• Used in smart homes and automation
🔹MCCB
• Protects against overload, short circuit, earth fault
• Higher current rating (up to 2500A)
🔹ELCB
• Older type, now mostly replaced by RCCB
• Protects mainly against electric shock
🔹ACB
• Uses air as arc extinguishing medium
• Used in low voltage, high current systems
🔹BOCB
• Uses oil to quench arc
• Large size and high maintenance
