Who it’s for and how it solves problems

This breaker is purpose-built for technicians dealing with maintenance, retrofit, or replacement tasks in 600V electrical systems. If you’re upgrading an older panel to meet current safety codes, performing a service disconnect upgrade, or restoring a critical line to full operation after a fault, the RKL2300 provides consistent protection with a form factor that fits your existing bolt-on infrastructure.

Use cases and practical applications

• Industrial control panels and service entrances requiring a robust 300A, 2-pole solution
• Retrofits in existing bolt-on panels where new equipment must align with established mounting footprints
• Emergency and critical load circuits where dependable, field-replaceable protection is essential

Installation and compatibility notes

• Always verify fit and ratings before ordering. The part number RKL2300 is the most reliable reference for compatibility with your panel.
• Confirm your enclosure accepts bolt-on circuit breakers of the RKL family and that the bus/ mounting footprint matches your panel design.
• Ensure the protected circuit requires 300A and the system operates at up to 600V AC (or specified 600V ratings) for safe, compliant operation.
• Follow all manufacturer installation guidelines and use appropriate protective equipment and lockout/tagout procedures during replacement or retrofit.

When you need a dependable, correctly rated bolt-on breaker for 600V infrastructure, the Westinghouse RKL2300 delivers the right balance of form, function, and field-verified compatibility. Check your panel’s specifications, reference the RKL2300 part number, and proceed with confidence toward renewed overcurrent protection.
