What is a Fusible Resistor?

A Fusible Resistor is a wire-wound resistor that is designed to burn open easily when the power rating of the resistor is exceeded.

Use of Fusible Resistors

In this way, a fusible resistor serves dual functions. When the power isn't exceeded, it serves as a resistor limiting current. When the power rating is exceeded, it functions as a fuse, burning up, and becoming an open in the circuit to protect components in the circuit from excess current.
