Surge Protection

Surge-Trap® Pluggable STPT12 Series - 8YPV is the PHOTOVOLTAIC range of combined Type 1+2/Class I+II devices intended for discharging lightning currents (10/350 μs) and protecting against induced voltage surges (8/20 μs), in accordance with IEC/EN 61643-31 standards. Ideal solution for protecting 6 MPPT, saving space and optimizing cost. DIN rail plug-in format.

Surge-Trap® Pluggable STPT2 Series - 5YPV is the PHOTOVOLTAIC range of Type 2/Class II devices intended for discharging induced voltage surges (8/20 μs), in accordance with IEC/EN 61643-31 standards. Ideal solution for protecting 2 or 3 MPPT, saving space and optimizing cost. DIN rail plug-in format.

Surge-Trap® Pluggable STPT12 Series - AC-Reinforced is the series of combined Type 1+2/Class I+II devices intended for discharging lightning currents (10/350 μs) and protecting against induced voltage surges (8/20 μs), in accordance with IEC/EN 61643-11 . Suitable for the AC side protection of inverters or wind turbine generators with a nominal voltage of 800 V AC. The reinforced 3+1 variant ensures safe operation where high withstand voltage peaks are required or where DC offsets are induced in AC side.

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.

PV string boxes T2 is the series of DC photovoltaic surge protection junction boxes for inverters to IEC/EN standard. With surge protection type 2, such boxes are ready for installation and just need to be connected in parallel upstream of residential and lite comercial string inverters of several MPP trackers, mainly 1000Vdc rooftop installations. Available with MC4 or cable gland connectors and for one and two MPP tracker applications. Please consult for availability and models, for instance 5 pole and 8 pole SPDs.

Mersen’s Surge Trap STMT Series features low voltage surge protective devices suitable for both AC and DC voltage applications. This series is ideal for the protection of controls, power supplies, communication systems, and other sensitive equipment. With a slim design, these DIN-rail mount SPDs are ideal for limited space applications. The series is suitable for operating voltages of 12-230 VAC and 24-365 VDC and offers an optional dry contact feature for remote monitoring.
