Surge Protection

STP T23 20 is the series of combined Type 2+3/Class II+III devices for discharging voltage surges while providing a very fine voltage protection level, in accordance with EN/IEC 61643-11. Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream such as STP T2 40 SPDs. These SPDs should be installed as close as possible to the equipment being protected.

STS PLC is the series of surge protection devices for digital signals and in particular for programmable logic controllers. The range offers a number of voltages and number of protected lines for a variety of applications as well as a terminal block ultra-slim format. These are protectors for a final step of very fine protection to be installed as close as possible to particularly sensitive equipment connected to these communications lines.

PCB Socket 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.
