Westinghouse | RK3100 | Circuit Breaker | 100A | 3-Pole | 600V

Westinghouse RK3100 Circuit Breaker — a rugged, three-pole safety device designed for 3-phase electrical systems. With a 100A rating and 600V capacity, it delivers reliable overcurrent protection for maintenance, retrofit, and replacement projects in commercial and industrial panels.

Designed to match Westinghouse specifications, the RK3100 is identified by its part number, which remains the best reference for compatibility across panels and assemblies. Before you order, confirm fit and ratings against your panel labeling to ensure a seamless swap.

• Amperage: 100 A
• Poles: 3-Pole (three-phase protection)
• Voltage: 600V
• Best uses: maintenance, retrofit, and replacement in compatible electrical panels
• Compatibility tip: Part number RK3100 is the best reference for compatibility; verify fit and ratings before ordering

Ideal for:

• Facilities with three-phase distribution needing reliable fault protection
• Industrial control panels undergoing upgrades or modernization
• Replacement projects requiring alignment with a specific RK-series or Westinghouse-compatible part

With the RK3100 in service, you gain predictable performance and quick fault isolation in demanding environments, helping protect motors, drives, and connected equipment from overloads and short circuits. The 3-Pole design ensures balanced protection across all phases, reducing the risk of uneven current draw and panel downtime.

Compared to generic substitutes, the RK3100 provides a documented part reference, tested compatibility with Westinghouse systems, and straightforward replacement in panels built for 3-phase, 600V service. Its form factor and ratings align with standard electrical distribution equipment, making it a safer, more reliable choice when upgrading or replacing aged breakers.

• Check labeling: Ensure your panel is rated for 100A, 3-Pole, 600V and that RK3100 is listed as a compatible replacement.
• Safety first: Disconnect power and follow local codes during installation; verify there is no residual energy in the circuit before servicing.
• Installation tips: Follow panel manufacturer guidance for mounting and wiring, and verify compatibility with your specific setup.

The Westinghouse RK3100 is a dependable, standards-aligned choice for professionals who demand precise compatibility and solid protection in 3-phase electrical systems.
