A residual load circuit breaker (1) includes a rotary switch body (23), which includes a contact blade (24, 25, 26, 27), that is rotatable about an axis (A) and is arranged between a feed line connection (20) and a discharge line connection (21), and includes end-side contact surfaces (28, 29, 30, 31) protruding in a radial direction. The contact surfaces, in a closed rotary position (S1) of the rotary switch body (23), are in touching contact with the feed line connection (20) and with the discharge line connection (21). In an open rotary position (S2) of the rotary switch body (23), the contact surfaces are each spaced with respect to the feed line connection (20) and with the discharge line connection (21). The residual load isolating switch (1) is rotationally limited in one rotational direction for performing switching movements and can be actuated unidirectionally and cyclically.
