Westinghouse | RK3100L | Circuit Breaker | 100A | 3-Pole | 600V

The Westinghouse RK3100L Circuit Breaker is a purpose-built protection device designed for reliable overcurrent protection in 3-phase electrical systems. With a 100A rating, 3 poles, and a 600V maximum, it’s an ideal choice for maintenance, retrofit, and replacement projects where exact specifications matter. Rely on the RK3100L to safeguard industrial and commercial panels, feeders, and equipment without compromising on performance or compatibility.

• Amperage: 100A
• Poles: 3-Pole
• Voltage rating: 600V
• Model reference: RK3100L
• Brand: Westinghouse

Designed to fit in panels and systems that require a three-pole, 100-amp protective device, the RK3100L is particularly well-suited for three-phase motors, pumps, and other equipment that rely on balanced phase protection. It simplifies retrofit projects by matching the precise part number, making cross-reference and compatibility checks straightforward for technicians and procurement teams.

Why choose this specific Westinghouse breaker?

• Precision compatibility — the RK3100L is the best reference for ensuring you’re ordering the right replacement or retrofit component for your existing panel or distribution setup.
• Clear fit guidance — notes emphasize confirming fit and ratings before ordering, helping you avoid mismatches that could delay installation.
• Reliability in demanding environments — built to handle routine overcurrent protection in 3-phase systems, keeping critical equipment protected and reducing unplanned downtime.

Use scenarios and practical considerations:

• Maintenance and replacement — swap in the RK3100L when a legacy breaker in a 3‑pole, 600V system reaches end of life or requires an approved equivalent for continued operation.
• Retrofit projects — upgrade or update panels where the existing component needs to meet updated ratings or form factors while preserving electrical protection standards.
• New installations with legacy compatibility — integrate into systems that specify the RK3100L model to ensure consistent trip characteristics and coordination with neighboring protection devices.

Implementation tips for best results

• Always verify the exact panel compatibility by cross-referencing the part number RK3100L with your panel manufacturer’s documentation before purchase.
• Check the system’s required voltage class and the 100A current rating to ensure proper coordination with upstream protective devices and downstream conductors.
• Maintain proper storage and handling practices for replacement breakers to prevent corrosion or mechanical damage prior to installation.

If you’re seeking a dependable, specification-aligned solution for safeguarding 3‑phase circuits at 600V, the Westinghouse RK3100L 100A 3-Pole Circuit Breaker delivers consistent performance, straightforward compatibility checks, and clear guidance for maintenance, retrofit, or replacement projects. Use the part number as your primary reference to ensure a precise match in your electrical system.
