Eaton CHF320SW Circuit Breaker - UL Listed
Part Number: CHF320SW
Quick Summary
Eaton CHF320SW Circuit Breaker provides reliable three-pole protection for 240 V electrical panels. Many engineers struggle to find plug-on, switching-neutral breakers that meet tight installation schedules and space constraints. UL Listed and HACR Rated certifications ensure safety and code compliance, while the 10 kAIC interrupt rating supports robust short-circuit protection. Designed for quick, dependable installation, it accepts #14-6 Cu/Al wire at 60°C or 75°C insulation and integrates with standard CH mounting rails. The result is reduced wiring complexity, lower labor costs, and improved panel reliability through a compact, economical thermal-magnetic solution suitable for industrial control, HVAC, and power distribution applications. This is especially valuable for retrofit projects where downtime must be minimized and panel space is at a premium.
