The Littelfuse EA1-B0-22-620-61C-FB is a single-pole magnetic circuit breaker with a hydraulic delay mechanism, designed for overcurrent protection in industrial and commercial applications. It is rated for 20A continuous current at 277V AC, providing reliable circuit interruption under fault conditions.
The breaker uses a magnetic (hydraulic delay) trip characteristic, which offers precise and repeatable performance over a wide temperature range. The lever actuator allows for manual on/off control and visible trip indication. This component is panel mounted, making it suitable for integration into control panels, power distribution units, and equipment enclosures.
The EA1-B0-22-620-61C-FB carries approvals from UL508, UL1077, CSA, and CCC, indicating compliance with North American and international safety standards for industrial control equipment and supplementary protectors.
