FIELD: electricity.
SUBSTANCE: according to the invention, the first function unit, having the mechanical breaker, comprises the first fusible element. The second functional unit arranged in the form of overload protection comprises the second fusible element. Each functional unit is arranged in body, besides, there are side oppositely arranged covers on body, and fusible conductors are installed inside body and are electrically connected to covers. The first and second functional units are connected electrically in parallel, besides, this parallel connection is connected serially with overvoltage protection device. Functional units form a common mechanical joint, besides, each case is surrounded with a separate elastic shell or another, also elastic, body, or both bodies are surrounded with common elastic shell or other, also elastic, body.
EFFECT: increased resistance to pulse current and efficiency.
