Important notes at the end of this document.

Application



Inrush current limiter for smoothing andDC

link capacitors



To replace high-power fixed resistors for

capacitor charging



Overcurrent and short circuit protection

Features



Lead-free terminals



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 Vmax even without

additional current limitation



Marking: Type, manufacturer's logo,

reference temperature in °C and date code

YYWW


