E1020 - 20Amp Circuit Breaker

E1020 - 20Amp Circuit Breaker

When you're maintaining an existing electrical system, finding the right replacement circuit breaker is about more than matching amperage alone. The E1020 20 Amp 1-Pole Thermal-Magnetic Circuit Breaker is designed for applications that require a Type E breaker with a 20A rating, 120VAC operation, and a 10kA interrupting capacity. Built for compatibility in existing installations, this breaker helps keep electrical distribution systems operating as intended without altering the original equipment configuration.

The E1020 features a thermal-magnetic trip mechanism, providing protection against both sustained overload conditions and short-circuit events. Its thermal element responds to prolonged overcurrent situations, while the magnetic trip reacts quickly when fault currents occur. The breaker also incorporates a non-interchangeable trip unit, helping maintain the original protection characteristics specified for the equipment.

With its compact footprint and included load terminals, the E1020 is well suited for maintenance, repair, and replacement projects in commercial, industrial, and institutional environments. Rated for operation in ambient temperatures up to 40°C, this breaker is built to last and designed to provide dependable circuit protection when installed in compatible equipment.
