⚡️ Miniature Circuit Breaker (MCB) — The Silent Guardian of Every Electrical System!

An MCB protects your wiring and appliances from overload and short circuit conditions.
It automatically trips when unsafe current flows — preventing fire hazards and equipment damage 🔌🔥

🧠 Quick Concept:
Moderate Overload: Thermometal bends → trips the circuit

Short Circuit: Solenoid plunger activates → instant disconnection

💡 Essential topic for JE, AE, Electrical Engineering, and Technician Exams!
