Surge arrester KNX-Bus BXT ML4 B 180 (920 310)
Type: DEHN 920 310 Surge arrester KNX-Bus BXT ML4 B 180 (4 cores)
EAN: 4013364109124
Assembly: must be purchased together with the base BXT BAS (not included in the package)
Space-saving four-pole lightning arrester module with LifeCheck for almost all applications. Can be used in conjunction with a superior type 2 surge arrester or combination arrester with a lower or equal voltage level. LifeCheck detects thermal or electrical overload conditions after which the arrester must be replaced. The display is contactless using DEHNrecord LC / SCM / MCM.
