<p>The earth leakage current circuit breaker has a housing contg. a current summation transformer, switching contacts and terminals, switch mechanism with trigger circuit. The housing also encloses a control unit. The axis of symmetry of the transformer (2) and the plane of symmetry of the switching mechanism (7) are arranged in the plane of symmetry of the housing (1). The switching mechanism (7) has an L shape one branch of which fits into the housing (1). The transformer (2) is located in a compartment formed by the mechanism's (7) other branch and another part of the housing (1).</p> |
