Surge Protection for Power Lines

DIN-Rail IEC Type 2+3 / Class II+III

Surge-Trap® Monobloc STMT23 Series - 20kA Slim

STM T23 20 S 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. Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream. These SPDs should be installed as close as possible to the equipment being protected. Ideal for limited spaces. Wide range of voltage ratings.
