BA1-B0-52-620-C12-D Description

Short technical summary and product information.

The Littelfuse BA1-B0-52-620-C12-D is a 1-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in panel-mount applications. It is rated for 20A continuous current at 277V AC or DC, with a robust hydraulic-magnetic trip mechanism that provides accurate and reliable protection without thermal derating.

 

The breaker features a lever actuator for manual on/off control and is non-illuminated. It mounts directly to a panel and is approved by major international agencies including CCC, CSA, UL, and VDE, making it suitable for use in industrial, commercial, and lighting control systems. The hydraulic delay characteristic minimizes nuisance tripping during inrush currents while ensuring fast response to sustained overloads.
