Q2431-40 - 40A Circuit Breaker

Q2431-40 - 40A Circuit Breaker

The Q2431-40 circuit breaker provides reliable protection for existing electrical systems that require a 40 amp, three-pole breaker. Electricians and maintenance teams use this breaker to replace worn or damaged units in compatible panels without changing the original layout or wiring. It carries a 10,000 AIC rating at 240 VAC and interrupts fault current effectively in commercial and light industrial applications. Because it matches the original form and electrical ratings, it installs directly into panels designed for this frame type.
