Abstract
The disclosure relates to an electrical circuit breaker for protecting a power distribution system in an industrial plant (30) with electrical consumers (5) distributed in the plant. Electrical power is supplied to the electrical consumers (5) via a power-supplying line branch (7) of the power distribution system. For protecting the consumers, an electrical circuit breaker (20) is arranged in the power-supplying line branch (7). The electrical circuit breaker (20) is accommodated in a closed housing (10). The housing (10) has at least one first contact (11) for the power-supplying line branch (7) and at least one second contact (12) for an electrically protected line branch (8) which is connected to the electrical consumer (5).
