Three-phase Inrush current limiter
2 - 32 A

Inrush current limiters find widespread use in the field of electronics, electrical engineering, or more specifically in AC technology. As the term inrush current limiter already indicates, this technology is required at the moment of switch-on of electronic devices in order to protect them from high inrush current. At the moment of switching on, the inrush current of several multiples of the actual rated current can flow in a short time. Inrush current limiters are therefore used to prevent upstream fuses from blowing and to minimize high loads on capacitors.
