Fusible Resistors

Fusible resistors, also known as fuse resistors, are special types of resistors that have an added function of self-protection. They are designed to protect circuits from overloading and overheating by acting as fuses when exposed to excessive currents or power surges.

Fusible resistors work by including a fusible element within the resistor itself, such as a small metal wire or a coating of fusible alloy. When the current or power in the circuit exceeds the rated value of the resistor, the fusible element melts, creating an open circuit and disconnecting the power source from the rest of the circuit. This interrupts the flow of current, preventing damage to the circuit and the components it connects.

Fusible resistors are commonly used in applications where circuit protection is critical, such as in power supplies, motor controls, and electronic lighting systems. They are often employed in situations where conventional fuses or circuit breakers may not provide adequate protection or where space is limited. Fusible resistors are available in a range of resistance values, power ratings, and tolerances to suit various applications. They are typically marked with a symbol or a code to indicate their fusible nature.
