A new range: Surge Protection for industry applications
Our strong team of products ensures reliable surge protection for harsh industry environments. The solutions increase system availability as the main fuses don’t fail. They are important for the industry sector, data centres and hospitals. In large systems they save space and costs without prefuses. The new range also comprises 400/690 V applications, such as for free-standing PV systems and wind power plants in demanding energy infrastructures worldwide.
