NC301 1A 3P 400V Circuit Breaker | AmpState

The NC301 1A 3P 400V Circuit Breaker from AmpState is a purpose-built protection device designed for panelboards, load centers, and distributed electrical systems. When a direct part-number match matters—for maintenance inventories, panel builds, or retrofits—this NC301 stands out as a dependable, field-tested choice.

Key reasons to choose the NC301 for your three-phase distribution:

• Three-pole design for balanced protection across all phases in 400V AC systems, with a precise 1 A rating to guard control circuits and light loads without nuisance trips.
• Direct part-number compatibility: ideal for replacing a failed unit in existing installations or stocking spare breakers that align exactly with spec sheets.
• Versatile application across panelboards, load centers, and electrical distribution panels—supports quick swaps and consistent performance in commercial and light industrial environments.
• AmpState support for compatibility verification: if you’re unsure about fit, our team can help confirm whether NC301 matches your equipment’s part-number requirements.

What this means in everyday use:

• In a three-phase motor control or processing panel, the 400V rating accommodates typical line-to-line voltages found in many regions, while the 1 A trip threshold protects downstream devices without overreacting to startup surges.
• During preventive maintenance, keep an exact NC301 on hand so replacements slide into place without frame modifications or rewiring.
• Stock management becomes simpler when your inventory aligns with a single, standard part number for multiple projects, reducing confusion and purchase errors.
