MCB (Miniature Circuit Breaker)
These are the most common type of circuit breaker found in homes and small businesses. They protect electrical circuits from overloads (excessive current) and short circuits.
MCCB (Molded Case Circuit Breaker)
Used in industrial and commercial settings, they can handle higher currents and voltages than MCBs and offer better protection against faults and overloads.
RCCB (Residual Current Circuit Breaker)
Also known as RCDs (Residual Current Devices), these are safety devices that detect earth leakage currents. They trip the circuit to prevent electric shocks.
ELCB (Earth Leakage Circuit Breaker)
Similar to RCCBs, but generally older technology. They are being phased out in favor of RCCBs. RCBO (Residual Current Circuit Breaker with Overcurrent Protection)
Combines the functions of an RCCB and an MCB in a single unit, offering both earth leakage and overload protection.
AFCI (Arc Fault Circuit Interrupter)
Designed to detect and interrupt electrical arcs that can lead to fires, primarily used in residential settings to protect against electrical fires.
GFCI (Ground Fault Circuit Interrupter)
Similar to RCCBs, these devices are specifically designed for outdoor use or areas with high moisture.
They protect against electric shocks in wet environments.
WIFI CB (WiFi Circuit Breaker)
This is a modern type of circuit breaker that can be controlled remotely via a WiFi network. It allows for convenient switching of circuits on and off using a smartphone app.
ACB (Air Circuit Breaker)
These are used in high-voltage applications such as power distribution systems. They can handle very high currents and voltages.
VCB (Vacuum Circuit Breaker)
These are used in high-voltage applications where rapid switching is required. They are known for their fast operation and high reliability.
MPCB (Motor Protection Circuit Breaker)
This device is specifically designed to protect electric motors from overloads, short circuits, and phase failures.
