• Reference: Part number S5N-3P-300A

Why choose the S5N-3P-300A for your panel

This ABB circuit breaker is designed to slot into panels and assemblies that expect the S5N series form factor and electrical ratings. The 3-pole configuration supports balanced protection across three-phase systems, helping prevent phase imbalances that can harm motors and drives. The 600V rating provides headroom for typical industrial distributions, enabling safe interruption of fault currents while supporting efficient system operation.

Ideal use cases

• Retrofits: replace aging breakers in existing ABB or compatible panels without compromising electrical specs.
• Maintenance spares: keep on hand for quick swaps during scheduled downtime.
• New builds: specify for three-phase power distribution where 300A protection is required.
• Motor control centers and industrial power distribution: reliable fault interruption for motors and equipment.

Compatibility and installation guidance

For the most reliable results, confirm fit and ratings before ordering. The S5N-3P-300A part number is the best reference to ensure compatibility with your panel and busbar configuration. When installing, work with a qualified electrician and follow your enclosure manufacturer’s instructions and local electrical codes.
