BA2-B0-26-450-1B1-C Description

Short technical summary and product information.

The BA2-B0-26-450-1B1-C is a 2 pole magnetic (hydraulic delay) circuit breaker manufactured by Littelfuse. It is designed for overcurrent protection in electrical circuits, offering a current rating of 5A and a voltage rating of 277V. The hydraulic delay mechanism provides a time-delayed trip characteristic, allowing brief current surges without nuisance tripping.

 

The breaker features a lever actuator for manual on/off control and is panel mounted for secure installation in enclosures or control panels. It has no illumination, making it suitable for applications where visual indication is not required.

 

Approved by CCC, CSA, and UL agencies, this circuit breaker meets international safety standards. The 2-pole configuration allows simultaneous disconnection of both live conductors, enhancing safety in single-phase or two-phase systems.
