Westinghouse | 1313571 | Circuit Breaker | 1-Pole | 277V

Meet the Westinghouse 1313571 — a purpose-built 1-Pole circuit breaker designed specifically for 277V circuits. This unit excels in maintenance, retrofit, and replacement projects where exact specifications matter, ensuring you can keep commercial and specialty electrical systems running safely and reliably.

Key details

• Pole: 1-Pole
• Voltage rating: 277V
• Part reference: 1313571 for precise compatibility

Notes: Confirm fit and ratings before ordering. The part number 1313571 is the best reference for compatibility with your panel or equipment.

Who this is for

Ideal for electricians, facility managers, and technicians performing panel maintenance, retrofits, or replacements in commercial environments that run 277V circuits. If your setup demands a single-pole breaker with a 277V rating, this Westinghouse unit is designed to slot into compatible panels with confidence.

What problems it solves

• Provides safe, code-aligned interruption for a single 277V line, helping protect wiring and connected equipment from overloads.
• Delivers a reliable replacement option when upgrading or restoring breakers in panels that require the 1313571 reference.
• Supports retrofit projects where existing equipment or panelboards specify a 1-Pole, 277V solution, reducing compatibility guesswork.

Use cases and practical scenarios

• Replacing a failed or nuisance-tripping 1-Pole breaker in a 277V lighting or equipment circuit within a commercial space.
• Retrofit projects where a panelboard or switchgear requires a 1-Pole, 277V breaker with a matching Westinghouse part number for proper fit.
• New installations in settings that standardize on Westinghouse 1313571 for consistency across multiple circuits and panels.

How this unit compares to alternatives

Unlike generic substitutes, this breaker is specified for 277V single-pole applications and aligns with the Westinghouse family’s design and mounting geometry. When your project hinges on exact part references for compatibility, the 1313571 ensures you’re choosing a unit that will drop into the correct slots, terminate with standard wiring methods, and align with your panel’s ratings—reducing installation friction and post-install checks.

Practical tips for a smooth install

• Always verify that your panel accepts 1-Pole 277V breakers and that the 1313571 matches the required part number for your specific panel model.
• Have a licensed electrician perform the replacement to ensure proper torque on terminals and secure mounting.
• Keep a spare 1313571 on hand for planned maintenance or future retrofit needs to minimize downtime.
