Abstract
The utility model discloses a small plug-in type leakage circuit-breaker, comprising a leakage circuit-breaker body. The leakage circuit-breaker body comprises a shell, a circuit-breaking section and a leakage acting section. The utility model is characterized in that the shell is provided with a pins; the pins is plugged into an installation seat which has wire connecting terminal at both sides and has a fastening device of rail at the lower end. With above design and structure, the utility model is convenient in exchange only pulling out the circuit-breaker body without any extra tools. When being installed, the installation seat is fixed with standard rail or bolt; and then the wire connecting terminal at the sides of the installation seat is connected with the power wire and the unloading wire; and the circuit-breaker body is plugged in the installation seat; therefore, the utility model has the advantage of easiness in installation.
Description
Affiliated technical field
The utility model belongs to the low-voltage electrical apparatus field, refers in particular to the small-sized residual current circuit breaker of a kind of plug-in type.
Background technology
Residual current circuit breaker is made up of breaker portion and electric leakage action part, comprise shell, fixed contact, dynamic static joint, operating mechanism, zero sequence current mutual inductor, electronic circuit board, leakage tripping device, its operation principle is: when residual current circuit breaker during in normal operation, pass each phase current balance at the turnover two ends of zero sequence current mutual inductor, vector and be zero, zero sequence current mutual inductor secondary side no-output; When electric leakage or person electric shock occurring, the zero sequence current mutual inductor secondary coil induces residual current, residual current amplifies through electronic circuit, leakage tripping device is subjected to this current excitation, make circuit breaker tripping and open circuit, promptly when residual current equaled specified residual current acting value (I Δ n), leakage tripping device will move, and makes breaker open operation.At present, the small-sized residual current circuit breaker of selling on the market is installed whole parts and is comprised binding post in the one body type case, needs during replacing to unclamp binding post when charged () with Insulating screw driver, changes trouble.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of plug-in type small-sized residual current circuit breaker, and it need not to use any instrument just can be convenient for changing or to install.
For achieving the above object, the solution that the utility model is taked is: the small-sized residual current circuit breaker of a kind of plug-in type, comprise the residual current circuit breaker main body, the residual current circuit breaker main body is made up of shell, breaker portion and electric leakage action part, it is characterized in that shell has pin, pin inserts both sides has binding post, lower end that the mounting seat of track clamping body is housed.
Because the utility model is provided with both sides and has binding post, lower end that the mounting seat of track clamping body is housed, only need pull out the residual current circuit breaker main body during replacing and need not to use any instrument, change very convenient.During installation, first employing standard guide rail is installed or is adopted screw that mounting seat is installed, and mounting seat both sides binding post connects power line and load line, inserts the residual current circuit breaker main body again, has the advantage of rapid and simple installation.
