NA320 | Circuit Breaker | 20A | 3-Pole | 240V | Plug-In

Engineered for industrial environments, the NA320 circuit breaker delivers precise overcurrent protection for 3-phase 240V systems. With a 20A rating, a 3-pole configuration, and a convenient plug-in design, this unit is built for fast, reliable field replacement and retrofit in compatible panels.

• Amperage: 20A
• Poles: 3-Pole
• Voltage: 240V
• Plug-In: Quick-install plug-in design for streamlined service
• Ideal for: Maintenance, retrofit, and replacement projects in industrial panels
• Compatibility reference: Part number NA320 is the primary reference for fit

Why NA320 stands out in a crowded field is its purpose-built alignment with three-phase power and 240V distribution. The 3-pole arrangement ensures synchronized protection across all phases, helping to safeguard motors, pumps, and controlled loads from overcurrent events. The plug-in format minimizes panel downtime during swaps, letting technicians complete replacements without extensive rewiring or panel modification.

Use-case scenarios you’ll appreciate:

• Stocking a maintenance inventory for facilities running three-phase equipment on 240V rails, ready for rapid swap-out
• Retrofits where existing breakers require identical form-factor and ratings to maintain panel continuity
• Emergency replacements in service or distribution panels where fast, clean plug-in installation reduces downtime

Important: Confirm fit and ratings before ordering. The part number NA320 is the most reliable reference to ensure compatibility with your panel and system requirements.
