WebOct 5, 2024 · The primary benefit of a fusible resistor is that its resistance limits inrush current. A fusible resistor that serves as the main overcurrent component in a power supply or charger can have a resistance of 10 Ω. A fuse, in contrast, has a resistance ranging from milliohms to hundreds of milliohms. Designers can combine a fuse with an … WebNeutral grounding resistors are power resistors used in power grounding of Y-connected generators. They are used to limit the fault current and transient over-voltages, and allow …
