NA30 | Circuit Breaker | 30A | 1-Pole | 120V

The NA30 circuit breaker is a purpose-built solution for protecting 120V circuits in maintenance, retrofit, and replacement projects. With a 30A rating and a single-pole design, it delivers reliable overcurrent protection while fitting neatly into standard 1-pole panels. Use the NA30 as the definitive compatibility reference when sourcing a replacement—the part number is the best way to match fit and ratings for your enclosure.

• 30A protection safeguards wiring, outlets, and connected equipment from overloads by interrupting excess current quickly.
• 1-Pole design is tailored for 120V branch circuits, delivering straightforward installation and minimal panel footprint.
• Industrial-grade reliability built for steady performance in service environments where uptime matters.
• Precise compatibility rely on the NA30 part number to confirm fit with your existing panel or enclosure before ordering.
• Practical use cases ideal for routine maintenance, panel retrofits, and replacement projects where exact spec matching is required.

Who benefits most: electricians, facilities managers, and maintenance teams managing 120V distribution across commercial spaces, light industrial sites, or controlled equipment rooms. This breaker is a smart choice when you need to standardize on a single part number across many panels, reducing stocking complexity while maintaining safety and compliance.

How it stacks up against alternatives: Unlike multi-pole or higher-voltage breakers, the NA30 focuses protection on a single hot conductor for 120V systems. Its 30A rating is tuned for typical branch circuits and control circuits, offering the right balance between protection and usable current for many installations.

Practical tips: before purchasing, verify that the panel accepts NA30 and that 30A, 1-Pole, 120V aligns with your circuit design. When installing, follow standard electrical safety practices: isolate power, ensure proper seating in the bus, and tighten terminals according to your panel’s guidelines. Keep a spare NA30 on hand for faster replacements during routine maintenance or retrofit projects.
