With their fast response time and low residual voltage curve, combined lightning and surge arresters protect sensitive installation parts particularly effectively and without wear.
FLT-SPP offers decisive advantages for planners, operators, and installers: protection against disconnection and accidental contact, low tightening torque, and a new plug-and-pull concept facilitate safe installation and maintenance. Double insulation between the main and auxiliary circuits meets the requirements of IEC 61343-11. Thanks to their narrow design (17.5 mm per track) and modular plug-in capability, the combined lightning and surge arresters can be used flexibly. Their fuse-free operation up to 315 A and suitability for installations up to an altitude of 5000 m make them particularly suitable for building, wind turbine, and telecommunications installations.
