Upgrade or replace your electrical protection with the Westinghouse 1313531 Circuit Breaker, a purpose-built solution for reliable, high-current service. This 300A, 2-pole breaker is designed for bolt-on mounting and can be a precise fit for panels that require a sturdy, secure, bolted connection at 600V. If you’re performing a retrofit, maintenance, or a targeted replacement, this unit offers a robust combination of current rating, voltage handling, and installer-friendly mounting.

• Amperage: 300A
• Poles: 2-Pole
• Voltage Rating: 600V
• Mounting: Bolt-On
• Part Number: 1313531

Why choose a bolt-on design? Bolt-on circuit breakers like this Westinghouse model provide a secure, vibration-resistant attachment to compatible panels, making replacements and retrofits cleaner and more dependable in demanding environments. The 2-pole configuration protects both live conductors and reduces the risk of parallel faults, which is especially important in higher-current applications or panels with shared neutral conductors.

Ideal use scenarios include:

• Retrofits in older panels that mandate bolted protection for high-current circuits
• Maintenance replacements where the exact part number ensures compatibility
• Upgrades in systems approaching the 300A main or feeder protection needs
• Replacement in commercial or light industrial settings where 600V operation is standard

Compatibility and installation notes

• The best reference for compatibility is the part number 1313531. Always confirm that your panel’s design accommodates a bolt-on 2-pole, 600V breaker with the same mounting footprint.
• Follow the panel manufacturer’s torque specifications and installation procedures for bolt-on breakers to ensure safe, reliable operation.
• Verify that the application’s voltage and current ratings align with your system requirements before ordering.

What makes this Westinghouse breaker stand out is its combination of precise 300A protection, two-pole configuration, 600V rating, and a bolt-on mounting style that supports secure, durable field replacements. It’s a practical, time-tested choice for electricians and maintenance teams who value exact-fit replacements and straightforward retrofits without compromising protection or performance.
