| Zusammenfassung: | A multi-terminal surge arrester (10) is proposed, which comprises an active part (12) extending along a longitudinal direction (14) of the surge arrester (10), a first electrode (20) resting against a first end (18) of the active part (12), and a second electrode (24) resting against a second end (22) of the active part (12), which second end (22) opposes the first end (18) in the longitudinal direction (14) of the surge arrester (10). The surge arrester (10) further comprises an insulating fixing device (26) mechanically connecting and fixing the first electrode (20) and the second electrode (24), and an insulating housing (38) arranged around the active part (12). The active part (12) comprises at least two metal-oxide based varistor elements (34) and a further electrode (40, 40a, 40b) arranged between the at least two varistor elements (34), which further electrode (40, 40a, 40b) provides an externally accessible electrical connection. Therein, the surge arrester (10) is adapted for being insulated by surrounding air. |
