Key specifications

• Part Number: 1310879
• Amperage: 90 A
• Poles: 3-Pole
• Voltage Rating: 600 V
• Application: Circuit protection for 3-phase, 600V systems

Why choose the Westinghouse 1310879

This circuit breaker stands out for installations that demand an exact OEM reference. The 1310879 designation is the clearest indicator of compatibility with Westinghouse panels and compatible equipment, reducing guesswork during replacements. Its three-pole design provides balanced protection across all three phases, helping maintain stable, safe operation in industrial and commercial environments.

Ideal use cases

• Maintenance replacements in existing 3‑phase 600V electrical panels.
• Retrofit projects where a 90A, 3-pole solution is required to match existing wiring and load profiles.
• Repairs and upgrades in facilities that rely on consistent, OEM-referenced components for reliability.

Installation and compatibility tips

Before ordering, confirm fit and ratings by comparing the panel’s labeling and OEM documentation. The part number is the best reference for compatibility, so verify that 1310879 aligns with your panel model and current electrical specifications. If you’re replacing an old unit, ensure the replacement matches the same amperage (90 A), pole configuration (3-pole), and voltage rating (600 V) to maintain proper protection and coordination with upstream devices.

Practical guidance for choosing this breaker

Choosing the Westinghouse 1310879 is about alignment and reliability. If your system operates on a three-phase 600V feed and calls for a 90A protective device, this breaker offers a straightforward, OEM-aligned solution that simplifies sourcing, installation, and future maintenance. By sticking with the exact part number, you minimize compatibility surprises and keep your electrical infrastructure operating with predictable protection.
