fusible resistor

fusible resistor

[¦fyü·zə·bəl ri′zis·tər]
(electricity)
A resistor designed to protect a circuit against overload; its resistance limits current flow and thereby protects against surges when power is first applied to a circuit; its fuse characteristic opens the circuit when current drain exceeds design limits.

However, in case of a short circuit at the primary side of the transformer, the wire wound fusible resistor F 1 becomes an open circuit to protect the system from safety hazards.
This fusible resistor with desirable lightning strike and pulse abilities protects against supply line voltage transients, and it restricts the peak in-rush current at switch on to suitable levels for the rectifier bridge, consistent with good EMC design.
The new version also features an updated component library that includes fuses, fusible resistors, shunt regulators, optocouplers, and heatsinks.
