Abstract
The utility model provides an undervoltage circuit breaker is crossed to knot formula plastics includes plastics circuit breaker upper cover (1), plastics circuit breaker base (2) and track plastics buckle (3). Its characteristics: the both sides face of plastics circuit breaker upper cover (1) respectively have two cubic holes (1 -1) and two sides of plastics circuit breaker base (2) convex each two buckles and carries out lock, internally mounted electron device, attachment rail plastics buckle (3) is located to the bottom face (2 -2) of plastics circuit breaker base (2), goes into the location department of the bottom face (2 -2) of position plastics circuit breaker bases (2) through little protruding son (3 -1) the installation of track plastics buckle (3), through track plastics buckle (3) thus elasticity thrust fix whole undervoltage circuit breaker is crossed to knot formula plastics on the attachment rail. This undervoltage circuit breaker is crossed to knot formula plastics adopts and goes up the method wiring of being qualified for the next round of competitions under the inlet wire, goes up the surface sign of inlet wire position (1 -4), uses N respectively, L, and expression inlet wire polarity uses IN to express to hold as the inlet wire, and lower surface of being qualified for the next round of competitions position (1 -3) carries out the sign, uses N respectively, L, and expression inlet wire polarity uses OUT to express as the leading -out terminal. Openly there be the hole site (1 -2) of two holes for this undervoltage circuit breaker is crossed to knot formula plastics working status indicator. Because the above -mentioned design of adoption, the product equipment is convenient, and the use can each other be joined in marriage with other circuit breakers on can making things convenient for all kinds of tracks better to adoption track plastics buckle to the installation is dismantled conveniently, but repetitious usage.
Description
Technical field
The utility model relates to a kind of for the overvoltage in low-voltage circuit and the under-voltage device causing the protection of electrical equipment permanent damage.
Background technology
At present, usually in low-voltage circuit, access current overload protector, and too high with the too low protective device of non-transformer voltage.Because current overload protector cannot to the too high of voltage and the too low protection causing electrical equipment permanent damage.
Summary of the invention
The purpose of this utility model is to overcome the weak point that current overload protector uses in too high with the too low environment of voltage, and a kind of button plastics overvoltage/undervoltage circuit breaker proposed.
In order to achieve the above object, the utility model adopts following technical pattern: button plastics overvoltage/undervoltage circuit breaker comprises plastics breaker upper cover (1), plastics circuit breaker base (2) and track plastic buckle (3).Its feature: the two sides of plastics breaker upper cover (1) respectively have each two button bits that two or four square holes (1-1) and two sides of plastics circuit breaker base (2) are protruded to fasten, inner mounting electronic device; Bottom faces (2-2) place attachment rail plastic buckle (3) of plastics circuit breaker base (2), be fit into the location place of the bottom faces (2-2) of a plastics circuit breaker base (2) by the small convex object (3-1) of track plastic buckle (3), whole button plastics overvoltage/undervoltage circuit breaker be fixed on attachment rail by the elastic thrust of track plastic buckle (3).The method wiring of outlet under this button plastics overvoltage/undervoltage circuit breaker employing upper incoming line, the outer surface mark of upper incoming line position (1-4), uses N respectively, L, represents inlet wire polarity, be expressed as end of incoming cables with IN; And the outer surface of lower wire outlet position (1-3) identifies, use N respectively, L, represent inlet wire polarity, be expressed as leading-out terminal with OUT.Front has two holes to be the position, hole (1-2) of this button plastics overvoltage/undervoltage working state of circuit breaker indicator light.
The utility model compared to existing technology tool has the following advantages: due to the light insulating properties of cost lower weight of plastics, and assembling product is convenient, adopts track plastic buckle can facilitate on all kinds of track, can interworking use better with other circuit breaker.This button plastics overvoltage/undervoltage circuit breaker obtains extensive use in low-voltage circuit is medium, and easy installation and removal, can repeatedly use.
