Key Specifications

• Amperage: 50A
• Poles: 3-Pole
• Voltage: 240V

Why the NA350 Matters

The NA350 is not just another breaker—it’s a targeted solution for scenarios where exact matching matters. Because the part number NA350 is the best reference for compatibility, you can streamline procurement and minimize compatibility risk. The 3-pole design ensures simultaneous protection across all phases in a three-phase system, while the 50A rating provides appropriate protection for medium-load industrial applications. This combination is ideal for projects that require a straightforward, reliable retrofit or replacement without sacrificing performance or safety.

Ideal Use Scenarios

• Maintenance on existing three-phase 240V panels where the circuit needs firm, predictable protection.
• Retrofit projects where a 50A, 3-pole, 240V solution matches old equipment specifications.
• Replacement of aging breakers in industrial systems that demand precise part-number compatibility.
• New installations or upgrades in 240V, three-phase environments requiring robust overcurrent protection.

Compatibility & Purchase Tips

Before ordering, verify fit and ratings to ensure seamless operation within your panel. The part number NA350 is your most reliable reference for compatibility, so cross-check it against your equipment documentation. If you’re replacing a failed unit or upgrading an existing installation, confirm that your system is a 240V, 3-pole configuration to match this breaker’s specifications.

Practical Considerations

• Use cases: maintenance, retrofit, and replacement in three-phase 240V systems.
• Target outcome: dependable interruption protection that aligns precisely with your existing electrical architecture.
• Safety first: ensure correct installation practices and adherence to local electrical codes when integrating the NA350 into any panel.
