The EA1-B0-26-630-12A-FB is a single-pole magnetic hydraulic delay circuit breaker manufactured by Littelfuse Inc. It is rated for 30A continuous current at 277V AC, making it suitable for branch circuit protection in industrial and commercial applications. The hydraulic-magnetic mechanism provides precise overcurrent protection with time delay characteristics, allowing for nuisance-free operation with inrush currents.
The breaker features a lever actuator for manual on/off control and is designed for panel mount installation. It carries approvals from CCC, CSA, UL508, and UL1077, ensuring compliance with North American and international standards. The compact 1-pole design saves panel space while delivering reliable circuit protection.
Typical applications include power distribution, control panels, and equipment protection where magnetic-only or thermal-magnetic breakers may not be ideal. The hydraulic delay provides stable performance across a wide temperature range without derating.
