ABB 2CTB815710R2600 Surge Protective Device OVR T1-T2 12.5-275s C QS
The devices are compatible with the System pro M compact series. The SPD with “TS” are optionally equipped with a auxiliary contact. The variants with “reserve varistor” (s) offer additional protection for the system, as the SPD is not completely disconnected from the mains at the end of its service life, but with an additional smaller varistor still guarantees basic protection and the system thus until the surge arrester is replaced is still protected.
