Inrush current limiters
Leaded disks
Inrush current limiter (charging resistor) for
smoothing and DC link capacitors
To replace high-power fixed resistors for
capacitor charging
Self-protecting in case of malfunction of
short-circuit relay or internal short circuit of
capacitor
Inrush current limiters are not damaged
when directly connected to V
