When your electrical panel requires reliable overcurrent protection for a 3‑phase, high‑current circuit, the Westinghouse RKL3300L circuit breaker delivers purpose‑built performance for maintenance, retrofit, and replacement projects.
The RKL3300L is a robust 300A, 3‑pole breaker rated for up to 600V, engineered to drop into compatible panels and provide dependable interruption when overcurrent events occur. For compatibility, the part number is the best reference—confirm fit and ratings before ordering.
In three‑phase electrical setups, a 300A, 3‑pole breaker protects all three hot legs, helping maintain system uptime and safe shutdown during fault conditions. Westinghouse’s RKL3300L is designed for reliability in commercial and industrial environments where a precise match to existing specifications is crucial.
Important note: Confirm fit and ratings before ordering. The part number is your best reference for compatibility, ensuring you get the correct breaker for your panel and electrical system.
