ABB 2CTB815710R2300 OVR T1-T2 4L 12.5-275s P QS Surge arrester 12.5 kA 1 pc(s)

Combined lightning and overvoltage protection device SPD type 1+2, for protection of low-voltage consumer systems against lightning currents and overvoltages. Tested SPD type 1 and type 2 according to DIN EN 61643-11. The devices can be used for use as overvoltage protection device according to VDE 0100 part 443 and part 534, as well as in the context of the lightning protection zone concept. The devices are compatible with the System Pro M compact series. The SPD with "TS" is optionally equipped with a potential-free changeover contact. The variants with "reserve varistor" (s) offer additional protection of the system by ensuring that the surge arrester is not completely disconnected from the mains at the end of its service life, but that an additional smaller varistor still guarantees basic protection and that the system is protected until the surge arrester is replaced.
