E3020 20 Amp Circuit Breaker

E3020 20 Amp Circuit Breaker

The E3020 circuit breaker is a 3-pole, 20-amp thermal-magnetic breaker designed for use in electrical distribution systems operating at up to 240VAC. It is commonly used in equipment that requires an E-frame breaker with a fixed, non-interchangeable trip unit, making it a practical solution when maintaining or servicing existing panelboards and distribution assemblies. The thermal-magnetic design provides two layers of circuit protection: the thermal element reacts to sustained overloads, while the magnetic mechanism responds instantly to higher fault currents such as short circuits. Rated for 40°C environments, the breaker is suited for typical electrical room conditions. This unit also includes load terminals, allowing for secure conductor connections during installation. With its defined ratings and frame compatibility, the E3020 is intended to provide the correct form, fit, and functional replacement in systems built for E-frame circuit breakers. Products in this category were designed for long service life and consistent protection when installed and maintained according to electrical standards.

Where It Works Best

• The E3020 3-pole 20-amp circuit breaker is typically used in commercial and industrial electrical systems that rely on E-frame breakers. It is often installed in panelboards, switchboards, and distribution equipment operating on three-phase 240VAC power. Facilities such as office buildings, manufacturing plants, institutional buildings, and maintenance environments may use breakers of this type when servicing equipment that requires the same frame style and electrical ratings.
