Two-pole SPD for operating current up to 20 A in looped-in wiring, with disconnection device without interruption of the power supply. A very low protection level allows the use as SPD type 3 (class III).
- SPD type 2 for DC power supplies
- Surge voltage protection for electrical and electronical devices
- Arrester status control display: LED green (readiness: on)
- With low-pass filter
- EAC certification
