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 200 A gG
Suitable for use in insulation-monitored systems due to combination of varistor and gas discharge tube free of leakage current
Extremely narrow design, just 12 mm per position
Free of leakage current
High-performance gas-filled surge arrester for N/PE protection
