Carling Technologies BA1-B0-34-450-121-D Circuit Breaker

Carling Technologies BA1-B0-34-450-121-D is a hydromagnetic (magnetic hydraulic) circuit breaker in the B Series, designed for panel mounting in control panels and equipment enclosures. This 1-pole, 5 A device provides AC protection with ratings listed at 277 V AC in Newark listings and 250 V AC in DigiKey catalogs, and it carries a 80 V DC rating in some data sources; it offers up to 5 kA short-circuit interrupting capacity and a trip time around 20 seconds for fault conditions. The hydraulic delay mechanism helps suppress nuisance trips during inrush or brief overloads while maintaining protection during sustained faults. RoHS compliant per distributor data, this compact lever-panel-mount breaker is suitable for protecting control circuits in industrial equipment and panel-mounted assemblies where reliable 5 A protection in a single-pole package is required.
