Functions:
Protects the electrical network from overvoltage caused by lightning strikes or grid disturbances.
Efficiently absorbs and redirects excess voltage to the grounding system, protecting connected equipment.
Fast response – <25 nanoseconds, ensuring reliable protection for sensitive electrical devices.
Suitable for installation in main electrical panels, safeguarding residential and industrial equipment.
Applications:
Residential buildings – Protects home electrical installations, household appliances, and electronics from overvoltage.
Industrial facilities – Secures industrial electrical equipment, automation systems, and production machinery.
Commercial buildings – Provides reliable protection for offices, shopping centers, and other business areas.
IT & Telecommunications sector – Used in electrical panels, server rooms, and data centers where uninterrupted power supply is crucial.
Pros:
High protection capacity – nominal discharge current of 20 kA, maximum 40 kA.
Fast response – activation time <25 ns, safeguards sensitive equipment from sudden voltage surges.
Easy installation – conveniently mounted on a 35 mm DIN rail.
Wide application – suitable for both residential and industrial electrical systems.
Cons:
IP20 protection level – must be installed in a closed electrical cabinet as it is not resistant to moisture or dust.
Single-pole protection – protects only one phase, so additional modules are required for three-phase systems.
