Скачать или смотреть How Does A Circuit Breaker Work?

Circuit breakers are the backbone of any electrical protection system. But how do they work? And what won’t they protect against? In this video, we take apart a BG Fortress circuit breaker to explore its inner workings, including overload protection, arc suppression, and magnetic trip mechanisms.

🔎 What You’ll Learn in This Video:
✅ How circuit breakers protect against electrical faults
✅ Why bi-metallic strips bend & trip the breaker
✅ How arc chutes and splitters stop dangerous electrical arcs
✅ What a magnetic trip mechanism is and how it reacts to faults
✅ The difference between uni-directional & bi-directional breakers
