Surge Protection

Surge Trap® K- K1 Series is a range of devices Type 1+2 / Class I+II which are designed to protect electrical installations from lightning strikes (10/350 μs) and induced voltage surges (8/20 μs). Ergonomic DIN Rail Pluggable format.

STL T23 PP is the series of robust 10 kV combined Type 2+3/Class II+III devices for discharging voltage surges while providing a very fine voltage protection level.
Suitable for protection of LED outdoor luminaires (street-light). Due to the exposure of the extremely sensitive LED electronics to lightning–induced overvoltages, STL T23 PP is a widespread market solution amongst OEM manufacturers of LED lighting systems.

STMZ T12 is the series of combined Type 1+2/Class I+II devices according to EN 61643-11 for use in the pre-counter area installed directly on 40 mm busbar system with coordination to terminal equipment (≤ 5m) Typ 1+2+3. Easy end fast fulfillment of VDE 0100-443/ -534. Depending on the product it can be used for TNC or TT-/TNS systems as well as for applications with or without external lighting protection systems.
