Abstract

The present invention refers to circuit breaker (10) comprising a first electrical contact (11) and a second electrical contact (12) that are arranged movably relative to one another in a movement direction (D). Preferably, the first electrical contact (11) is a pin (20) and second electrical contact (12) is a socket (21). In a contact position (CP) an outer contact surface (14) of first electrical contact (11) is in mechanical and electrical contact with an inner contact surface (15) of second electrical contact (12). Inside the first electrical contact (11) an interior hollow space (27) is provided that is in fluidic connection with at least one gas flow opening (24) provided in the area of a distal end (16) of first electrical contact (11). The interior hollow space (27) is in fluidic connection with a gas flow creating device (30). During a relative movement of the first electrical contact (11) and the second electrical contact (12) in movement direction (D) a gas flow (G) may be created through the interior hollow space (27) and the at least one gas flow opening (24) for cooling at least the distal end (16) of first electrical contact (11) in order to avoid creation of an electrical arc between the two electrical contacts (11, 12) or at least terminate the electrical arc as quickly as possible.
