These Protection Boxes with an IP65 enclosure provide a compact and preinstalled solution for applications in Power Centers, when there is no remaining space in existing distribution boards, for outdoor applications as well as for line termination at or close to the origin of the installation where the lines may be subject to direct lightning strikes.
They are available as:
- TN 40 ff with four voltage limiting SPDs (four modes of protection), for three-phase plus neutral 230/400 V TN-systems
- TT 40 ff with three voltage limiting and a voltage switching SPD (four modes of protection), for three-phase plus neutral 230/400 V TT-systems where connection type CT2 (3+1) is required according to HD 60364-5-534 and provide the following features and benefits:

• These protection boxes contain SPDs according Test class I and II / Type 1 and 2 (according to IEC/EN 61643-11);
• They are suitable for installation at zone boundaries up to 0A – 2 according to the lightning protection zones concept as defined in IEC 60305.
