BA1-B2-34-615-121-C Description

Short technical summary and product information.

The Littelfuse BA1-B2-34-615-121-C is a single-pole magnetic (hydraulic delay) circuit breaker designed for overcurrent protection. It is rated for 15A continuous current at 277V AC/DC. The breaker uses a hydraulic-magnetic mechanism that provides fast response to short circuits and delays on moderate overloads, making it suitable for applications with inrush currents. The lever actuator allows manual reset and switching. This breaker is panel mounted and is approved by UL, CSA, and CCC. It is non-illuminated. This component is commonly used in industrial control panels, power distribution systems, and equipment requiring reliable circuit protection.
