Axial Cemented Fusible Leaded Wirewound Safety Resistors

DESIGN SUPPORT TOOLS

ACxx-CS wirewound safety resistor series is designed to be

used as fusible safety resistor (or, AC mains input resistors).

The resistor fuses “without a bang” when AC mains voltage

is applied. At the same time, it acts as an in-rush current

limiting resistor for the normal operation. The specially

developed lacquer coating has superior thermal and

electrical insulating properties. This allows designers to

more easily meet the requirements of safety approval, whilst

eliminating the need to put additional fuses in series with the

input resistor.
