E3030 30 Amp Circuit Breaker

E3030 30 Amp Circuit Breaker

The E3030 circuit breaker is a 30-amp, 3-pole thermal-magnetic breaker designed for use in electrical distribution systems that require dependable circuit protection and compatibility with Frame Type E equipment. Built to provide consistent overcurrent and short-circuit protection, this breaker uses a non-interchangeable trip unit that helps maintain the intended protection characteristics of the circuit. Rated for 10kA interrupting capacity at 240VAC and 40°C operation, the E3030 is commonly used in commercial and industrial electrical panels where maintaining the original equipment configuration is important. Load terminals are included, allowing for straightforward installation in systems designed for this breaker type. These breakers were built to last and remain a practical solution for maintaining existing electrical infrastructure while preserving the correct form, fit, and function within compatible assemblies.

Where It Works Best

• The E3030 3-pole circuit breaker is typically used in electrical distribution panels and equipment where Frame Type E breakers are specified. It is often installed in commercial facilities, light industrial environments, and building electrical systems that rely on legacy panel configurations. This breaker serves as a form-fit-function replacement in compatible assemblies where maintaining the original amperage rating, interrupting capacity, and pole configuration is required. It helps support continued operation of existing electrical systems without altering panel design or protection settings.
