Westinghouse | RLM3500L | Circuit Breaker | 500A | 3-Pole | 600V | Bolt-On

Westinghouse RLM3500L Circuit Breaker is a heavy-duty bolt-on solution designed for demanding 600V three-phase systems. With a 500A rating and 3-pole configuration, this unit is built to handle the high-current protection needs of industrial and commercial electrical installations, while simplifying replacement and retrofit projects.

• Amperage and configuration: 500A, 3-Pole, 600V bolt-on circuit breaker.
• Mounting style: Bolt-On design for secure installation in compatible panels.
• Ideal use cases: Maintenance, retrofit, and replacement where exact specs are required in 600V three-phase systems.
• Compatibility guidance: Confirm fit and ratings before ordering; the part number is the best reference for compatibility.

Why choose the Westinghouse RLM3500L? This model combines a high-current rating with a rugged bolt-on design, delivering reliable protection for large motor loads, heavy equipment, and other three-phase circuits in commercial and industrial settings. The 3-pole arrangement ensures balanced interruption across all phases, helping protect conductors and connected equipment from fault conditions.

Practical guidance for purchasing and installation

• Who it’s for: Facility managers, electrical contractors, and maintenance teams responsible for upgrades, replacements, or retrofits in 600V three-phase environments.
• What to check before ordering: Panel compatibility with bolt-on RLM series, required amperage (500A), number of poles (3), and voltage rating (600V).
• Quick example scenarios: Replacing an aged 500A 3-pole breaker in a manufacturing line, retrofitting an older service panel to accommodate higher fault protection, or upgrading a facility’s motor control center where 600V three-phase protection is needed.

For best results, use the exact part number RLM3500L as your compatibility reference and verify fit and ratings against your existing panel specifications. This approach minimizes downtime and ensures a seamless upgrade or replacement while preserving the safety and reliability of your electrical system.
