BA1-B0-10-610-522-D Description

Short technical summary and product information.

The BA1-B0-10-610-522-D is a single pole magnetic circuit breaker from Littelfuse, utilizing a hydraulic delay mechanism for overcurrent protection. It is rated for a continuous current of 10A at a maximum voltage of 277V AC. The breaker features a lever actuator for manual reset and a panel mount design for secure installation in control panels and distribution boxes.

 

This circuit breaker carries approvals from CCC, CSA, UL, and VDE, ensuring compliance with international safety standards. The hydraulic magnetic trip mechanism provides time-delay characteristics, allowing for inrush currents without nuisance tripping while offering reliable short-circuit protection.

 

Designed for panel mount applications, the breaker has no illumination feature, making it suitable for environments where visual indication is not required. The single pole configuration makes it ideal for branch circuit protection in commercial and industrial power systems.
