PWR4522 Fusible Power Resistors
General Introduction
The PWR4522A Series of axial leaded wirewound resistors in a flameproof silicone coating are designed to fuse under abnormal
conditions such as sudden surges in voltage or circuit malfunctions. The resistor will fuse instantly upon the application of 220/240
mains voltage without flame or incandescent particles.
