Product Description

CPS block

Modular Surge Protective Device (SPD) designed according to standards UL 1449 3rd ed. and IEC 61643-11 for installation in main panels or distribution panels with high exposure ratings.

The CPS block provides comprehensive protection for a wide range of networks and voltages and also reduces maintenance costs due to its modular construction and the IAD® function.

• Nominal Rated 8/20 discharge current rating (In) of 20 kA per phase.

• Redundant Multi Discharge System varistor technology with individual disconnection of each MOV.

• Common and differential mode protection.

• EMI / RFI Filter.
