Key specifications

• Amperage: 350A
• Poles: 3-Pole
• Voltage: 480V

Why these specs matter in real-world scenarios:

• The 3‑pole design provides balanced protection for three‑phase systems, reducing the risk of uneven fault conditions and helping to maintain system stability during protection events.
• 350A capacity suits mid- to high-load industrial environments, offering robust protection for main feeders and critical subcircuits.
• 480V compatibility aligns with common industrial power distribution, enabling seamless integration into existing 3‑phase networks without adapters or aftermarket modifications.

This component is ideal for:

• Maintenance teams performing routine replacements on aging or worn breakers
• Retrofit projects updating panels to current protection standards
• Replacement stocking for plants that rely on precise spec alignment to minimize downtime
• Industrial facilities, manufacturing lines, and heavy equipment setups requiring reliable 3‑phase protection

Compatibility and ordering notes: Confirm fit and ratings before ordering. The XM433350 part number is the best reference for compatibility with your panel family and bus arrangement, ensuring a smooth swap with minimal disruption.
