### Q: What is the primary function of an arc chute/extinguisher in electrical equipment?
**A**: The arc chute/extinguisher safely extinguishes the electrical arc that forms when circuit breaker contacts separate under load, preventing equipment damage and ensuring operational safety by cooling and splitting the arc using deionizing plates.

### Q: What materials are commonly used in arc chute construction?
**A**: Arc chutes typically feature a heat-resistant ceramic or polymer chamber housing and deionizing splitter plates made from steel or copper alloys, chosen for their durability and ability to withstand high temperatures and electrical stresses.

### Q: How do splitter plates in an arc chute help extinguish electrical arcs?
**A**: Splitter plates deionize and cool the arc by splitting it into multiple smaller arcs, increasing surface area for heat dissipation and voltage drop, which quickly extinguishes the arc to prevent re-ignition and protect circuit breaker components.
