Westinghouse | RKL2125L | Circuit Breaker | 125A | 2-Pole | 600V

Meet the Westinghouse RKL2125L circuit breaker—a precise, dependable solution for protecting demanding circuits with a 125A rating and 600V maximum. This two-pole breaker is designed for maintenance, retrofit, and replacement projects where exact specs matter, helping you maintain safe, reliable electrical protection without guessing at compatibility.

Key specifications

• Amperage: 125A
• Poles: 2-Pole
• Voltage: 600V
• Part number: RKL2125L

Why this breaker stands out

• The 2-pole design ensures both hot legs in a circuit are interrupted together, providing coordinated protection for two-wire or multi-wire branch circuits.
• Clear compatibility reference: The RKL2125L part number is your best guide for matching fit and ratings, reducing the guesswork in panel upgrades and replacements.
• High-voltage capability: With a 600V rating, this breaker is suitable for commercial or industrial environments where higher-voltage circuits require solid, compliant protection.
• Adaptable for retrofit and maintenance: A practical choice when upgrading older panels or swapping out aging breakers to restore proper protection without overhauling the entire electrical system.

Use cases and ideal applications

This Westinghouse circuit breaker is ideal for projects that require exact specifications to maintain electrical safety and reliability. It’s particularly well-suited for:

• Retrofit installations where a 2-pole, 125A, 600V device matches the existing panel and conductors
• Replacement of aging or failed breakers in panels that require a matching RKL2125L reference
• Maintenance of critical circuits in commercial or light industrial setups that demand robust protection at higher voltages

Compatibility and installation tips

Before ordering, confirm fit and ratings to avoid mismatches. The part number is the most reliable reference for compatibility with your existing panel. For installation, follow standard electrical safety practices:

• Power down the main disconnect and verify absence of voltage before handling components
• Verify conductor sizes and panel requirements align with a 125A, 2-pole, 600V device
• Securely mount the breaker in the correct slot and torque terminals per the panel manufacturer's guidelines

What makes this a practical choice

If you’re upgrading a panel, performing routine maintenance, or replacing a unit that matches the RKL2125L specifications, this breaker offers a straightforward path to restoring proper protection without the headaches of mismatched parts. Its standard 2-pole configuration and 600V rating make it a reliable option for ensuring safe, consistent performance across your electrical system.
