Maintaining a safe and well-lit home is crucial for security and convenience. Understanding how Miniature Circuit Breakers (MCBs), Molded Case Circuit Breakers (MCCBs), and sensor lights function can help you make informed decisions about home safety and illumination.
1. Miniature Circuit Breakers (MCBs)
Function: MCBs are protective devices that automatically cut off the electrical circuit when an overload or short circuit is detected. They protect electrical circuits from damage caused by excess current.
How They Work:
- Overload Protection: When the current exceeds the rated value, the bimetallic strip inside the MCB heats up and bends, triggering the mechanism to open the circuit.
- Short Circuit Protection: In the case of a short circuit, a magnetic trip coil generates a strong magnetic field, rapidly opening the circuit to prevent damage.
Benefits:
- Prevents electrical fires caused by overheating.
- Protects appliances from damage due to electrical faults.
- Easily resettable
