Surge Protection

STM T1 50 is the most robust series of single pole Type 1/Class I lightning current arresters, able to discharge energy (current) from a direct lightning strike (10/350µs) on an external lightning protection system (LPS) or overhead supplies, in accordance with EN/IEC 61643-11. Suitable as the first step of protection in incoming power supply panels and areas with high exposure to lightning strikes, fitted with an external lightning protection system.

SurgeTrap Pluggable - STPT2 TERRA Series is the series of DIN rail devices for monitoring the grounding system from within the actual surge protection device. Type 2 surge protection according to IEC 61643-11.

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.

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)

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.

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.

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.
