Your advantages

Surge protection family for universal use with optimum energy coordination from the lightning current arrester to the device protection
Easy to maintain due to consistently pluggable protection modules
Excellent level of information provided by mechanical/visual status indicator and remote indication contact
More space in the control cabinet due to the narrow overall width of just 12 mm per position and use without separate backup fuse up to 315 A gG
Low voltage protection level at high continuous voltage for optimum protection of the subsequent installation
Extremely narrow design, just 12 mm per position
Varistor arrester with a low leakage current
