Key features & benefits

SB PCB is the series of socket bases that allow for integration of Mersen’s pluggable IEC surge protection cartridges directly on printed circuit boards. Those surge cartridges will be easily replaceable upon reaching their end of life. SB PCB is an optimal solution for the industry of power electronics: inverters, converters, control panels for railway, PV combiner boxes, machines, OEM equipment, etc. Key benefits are cost efficiency, space efficiency, no wiring and optimal voltage protection of sensitive electronics. Integration of surge protection on PCBs is often planned for at an early stage of development of the system. The surge sockets will be firmly fixed to the PCB during the wave soldering process. They’ll host the entire range of IEC surge protection cartridges AC & DC, T2 & T1.
