A fusing resistor is designed to protect a circuit against damage as a result of current or voltage overload.  The resistor limits current flow and protects the circuit by opening (stopping current flow) when current levels exceeds its fuse characteristic design limits. The resistor serves the dual functions of a fuse and a resistor to limit the current.

Riedon fusible resistors are normally wire-wound resistor designed to open at power levels specified by the application.  These resistors must be specially analyzed and designed for a customer application in order to assure that the fuse opens under the right conditions and within the time duration specified by the application.

Please contact Riedon to discuss your fusing applications.  We would be happy to work with you to develop a product for your requirements.  Call us to get more information.
