What happens here

The presenter displays a contactor and prompts the viewer to consider why it might have 12 terminals. The explanation reveals that such a high number of terminals is typically due to commercial facilities utilizing 3-phase electrical panels. Contactors are designed with terminals in multiples of three (e.g., 3, 6, 9, 12, or 15) to accommodate the three phases of power. Common phase wire color codes like Brown, Orange, and Yellow are mentioned in this context.

Goal: Understand the physical characteristics of a contactor and its relation to 3-phase power
