Westinghouse | 1313533 | Circuit Breaker | 350A | 2-Pole | 600V | Bolt-On

Engineered for demanding, high‑load electrical environments, the Westinghouse 1313533 circuit breaker delivers reliable overcurrent protection where it matters most. This 350A, 2‑pole unit is rated for 600V and uses a robust bolt‑on mounting design, making it a secure, field‑ready solution for panels that require a sturdy mating breaker.

• Key specs: 350A, 2‑Pole, 600V, Bolt‑On
• Part reference: The part number 1313533 is your best compatibility reference—confirm fit and ratings against your panel’s requirements before ordering.
• Designed for use cases: maintenance, retrofit, and replacement in industrial and commercial electrical distributions where a high‑capacity, bolt‑on breaker is required.

Why bolt‑on matters: a bolt‑on mounting provides a secure mechanical connection to the panel bus bars, reducing movement under heavy load and during fault conditions. This translates to steadier performance, longer service life, and easier field alignment during installation. Westinghouse engineers have focused on dependable trip characteristics and robust construction to protect circuits feeding large motors, feeders, and essential equipment.

Use cases and ideal applications

• Maintenance and retrofit projects in mid‑ to large‑volume electrical rooms where existing bolt‑on breakers are being upgraded to higher amperage protection.
• Replacement in panels that specify 2‑Pole, 600V protection for feeder lines and motor circuits.
• New installations in facilities that require a secure, bolted connection for dependable fault protection in demanding environments.

Compatibility and installation tips

Before ordering, verify that your panel accepts bolt‑on breakers of this size and rating. Use 1313533 as the compatibility reference, and follow the panel manufacturer’s torque and mounting guidelines to ensure a solid, code‑compliant installation. If you’re upgrading from a lower amperage unit, plan for any needed bus bar accommodations or wiring adjustments to accommodate the 350A continuous rating.

Who should consider this breaker

• Electrical pros handling maintenance, retrofit, or replacement in industrial settings with large feeders or motor circuits.
• Facility managers upgrading panels to higher protection levels, aiming for reliability and long service life.

Note: Always confirm fit and ratings with the panel manufacturer before purchase. The part number 1313533 is the most reliable reference for compatibility, and the bolt‑on design is integral to secure installation in appropriate systems.
