DIN Rail AC Surge Protective Devices Are Connected in Parallel and Use An MOV to clamp High-voltage Surges for the Protection of 1- and 3-phase Systems

Product Details

OBV5-C40 series

DIN Rail AC Surge Protective Devices are connected in parallel and use an MOV to clamp high-voltage surges. These devices are primarily used in the main electrical panel for the protection of 1- and 3-phase systems.


The surge arrestors OBV5-C40 meet the type 2 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary.
