Applications

Inrush current limiter (charging resistor) for

smoothing and DC link capacitors

To replace high-power fixed resistors for

capacitor charging

Features

Self-protecting in case of malfunction of

short-circuit relay or internal short circuit of

capacitor

Encased thermistor disk with clamp contacts

for high reliability

For high pulse currents and a high number of

operating cycles

Inrush current limiters are not damaged

when directly connected to Vmax even without

additional current limitation

Flame-retardant plastic case

Case material UL-listed

Sn-plated lead-free solder pins
