Surge Protection

Mersen’s TPMOV technology eliminates common failure
modes that occur in the field with standard metal oxide varistors.
Internally each component is comprised of a voltage clamping device and
a disconnecting apparatus that monitors the status of the metal oxide
disc making the TPMOV surge suppression component a fail-safe device. Upon failure the TPMOV surge suppression component is
also equipped with a visual pin indicator as well as a normally open
micro-switch providing remote indication, if applicable. Mersen’s
25TPMOV series surge suppression component is rated for 25kA - 8/20μs peak surge current and is
available for maximum continuous operating voltages (MCOV) from
150V to 320VAC.

Surge-Trap® Pluggable STPT2 Series - 8YPV 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 6 MPPT, saving space and optimizing cost. DIN rail plug-in format.

PV string boxes T1+2 is the series of DC photovoltaic surge protection junction boxes for inverters to IEC/EN standard. With surge protection type 1+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.

Surge-Trap® Pluggable STPT12 Series - 5YPV 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 2 or 3 MPPT, saving space and optimizing cost. DIN rail plug-in format.
