QB2430-15 - 15 Amp Circuit Breaker

QB2430-15 - 15 Amp Circuit Breaker

The QB2430-15 is a 15 amp, three-pole circuit breaker designed for electrical panels that use QB-style bolt-on breakers. It’s a practical solution when an exact match matters—especially in older commercial or industrial systems where the original panel layout and ratings need to stay intact. This breaker is built to match the physical size, mounting style, and electrical characteristics required for proper fit and dependable operation, making it a solid choice for routine maintenance and direct replacement work.

Key Features and Benefits
