EE3B050 - 50Amp Circuit Breaker

EE3B050 - 50 Amp Circuit Breaker

The EE3B050 is a 50 amp, 3-pole molded case circuit breaker built for use in three-phase electrical systems. It’s part of the EE3 frame series, so it’s typically used as a direct replacement in panels that already take this style of breaker. If you’re working on an existing setup and need something that fits and functions the same way, this is the kind of unit you’re looking for. It carries a 10k A.I.C. rating at 240VAC, which means it’s designed to safely interrupt fault currents within that range. The molded case helps keep the internal parts protected from dust, contact, and general wear. It’s rated for use in 40°C environments, which covers most standard operating conditions in commercial and light industrial spaces. Overall, it’s a straightforward breaker—no extras, just what’s needed to do the job and keep systems protected over time.

Material Compliance and Certifications

• This breaker is made using standard materials typical for molded case circuit breakers used in commercial and industrial electrical systems. It’s intended to meet general safety expectations for this type of equipment. As always, final approval depends on your local codes and the specific installation.

Where It Works Best

• This model is commonly used in existing panelboards and distribution systems that require an EE3 frame breaker. You’ll see it in commercial buildings, small industrial setups, and similar environments running three-phase power. It’s especially useful when you need to replace a breaker without changing the panel layout or setup.
