EE2B040 - 40A Circuit Breaker

EE2B040 - 40 Amp Circuit Breaker

The EE2B040 is a 40 amp, 2-pole molded case circuit breaker built for use in 240VAC systems. It’s part of the EE2 frame series, so it’s mainly used in setups where that specific frame type is already in place. If you’re replacing an existing breaker, this keeps things simple from a fit and compatibility standpoint. It handles standard overload and short circuit protection and carries a 10k A.I.C. rating, which lines up with many common commercial and light industrial applications. Rated at 40°C, it’s intended for normal operating environments—not anything extreme. Overall, it’s a straightforward breaker that does what it’s supposed to do and holds up over time.

Where It Works Best

• You’ll usually see this breaker in commercial panels, older distribution equipment, or anywhere an EE2 frame is already being used. It’s a good fit for maintaining existing systems—especially when you need the same size, rating, and layout without changing anything around it. Common uses include branch circuits, small equipment loads, and general power distribution in standard indoor environments.
