Inside a 3-Phase Molded Case Circuit Breaker Teardown & Explanation

Welcome back to another hands-on electrical vlog! In this episode, I’m taking apart a 3-phase, 3-pole Molded Case Circuit Breaker (MCCB) to reveal exactly what’s inside. What’s inside this MCCB? We’ll examine each major component — from the three bimetallic trip elements to the arc chutes — and explain how they work together to protect large three-phase electrical systems. You’ll see how overcurrent and short-circuit protection is achieved across all three phases, and why this type of breaker is essential for industrial and commercial power distribution. Why this teardown matters This demonstration is designed for electricians, students, and anyone curious about electrical safety gear. By tearing down this non-functional breaker, you’ll see the internal mechanics without risking a live installation.
