Surge Protection

STL T23 PP is the series of robust 10 kV combined Type 2+3/Class II+III devices for discharging voltage surges while providing a very fine voltage protection level.
Suitable for protection of LED outdoor luminaires (street-light). Due to the exposure of the extremely sensitive LED electronics to lightning–induced overvoltages, STL T23 PP is a widespread market solution amongst OEM manufacturers of LED lighting systems.

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.

POP CT is the series of combined power frequency overvoltage protection (POP) and surge protection device for discharging surge current in the first step of protection according to EN/IEC 61643-11. Intended for actuation on the contactor of an installation (not included). Suitable for the first stage of protection in commercial or other applications not exposed to direct strikes and with no external lightning protection system. These devices are suitable for installation in lighting panels.

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.

STE 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. Complete with a built-in powerful EMI filter. Suitable as the final stage of protection in installations with electromagnetic disturbances which might interrupt, degrade or limit system performance. Series connection for applications up to 20A rated current.

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. LCF Leakage current free T1+2 (no electrial loses)

STP T2 40 is the series of Type 2/Class II devices for discharging voltage surges, in accordance with EN/IEC 61643-11. Suitable for the second stage of protection in supply distribution panels in which Type 1 protection devices are installed upstream, or for the first stage of protection in commercial or other applications not exposed to direct strikes and with no external lightning protection system.

Surge-Trap® K - K2 Series is a range of devices Type 2/Class II designed to protect against induced voltage surges (8/20 μs).
