An HVDC circuit breaker unit (1) with an interrupter branch (2) extending between a first node (3) and a second node (4) comprising a vacuum interrupter (5) connected to the first node (3), and a gas interrupter (6) connected to the second node (4) of the circuit breaker unit. The vacuum interrupter (5) is connected to the circuit breaker unit (1) at a third node (7) such that the gas interrupter (6) is electrically connected in series to the vacuum interrupter (5). A first movable contact member (11) of the vacuum interrupter (5) and a second movable contact member (12) of the gas interrupter (6) are operatable by at least one Thomson coil drive. An arrestor branch (8) comprising a first non-linear resistor (9)is connected to the first node (3) and the second node (4).read more
