The Littelfuse BA1-B2-24-615-121-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical systems. It is rated for 15A continuous current at 277V AC, making it suitable for branch circuit protection in commercial and industrial applications.
The breaker uses a magnetic hydraulic-delay mechanism that provides predictable trip characteristics and resistance to nuisance tripping from transient currents. The lever actuator allows for manual on/off control and visible trip indication. With a panel mount configuration, it integrates into standard control panels and equipment enclosures.
This breaker is approved by UL, CSA, and CCC, supporting use in North American and international installations. It is a non-illuminated unit, simplifying wiring and reducing power consumption. The single-pole design protects one phase or line conductor.
Typical applications include power distribution, motor control circuits, and equipment protection where reliable overcurrent interruption is required. The magnetic trip mechanism offers fast response to short-circuit conditions while the hydraulic delay accommodates inrush currents.
