Small Miniature Circuit Breaker Protection For Household Total Open Air Switch

small circuit breaker breaker DZ47 short-circuit protector for household total open air switch

Product description

 
   DZ47 small circuit breaker is the current that can connect, load and break normal circuit. A mechanical switching device that can also connect and carry certain time and sectional current under specified abnormal conditions.

Product features

  1. strict product structure, meticulous and comprehensive protection

  2. advanced production process and beautiful appearance

  3. safety insulation of fire retardant and high flame retardant material

Use of attention

  1. the load connection of the leakage circuit breaker must pass through the load end of the circuit breaker, and no any line or zero line of the load does not pass through the leakage circuit breaker. Otherwise, the "leakage" will result in the circuit breaker closing, causing "misoperation". Besides, in order to protect the line and equipment more effectively, the leakage circuit breaker and fuse can be used together.

  2. when the circuit is connected, check whether the wiring is correct. It can be checked by the test button. For example, the breaker can be correctly broken, indicating that the installation of the leakage protector is correct, otherwise, the line should be checked and the trouble should be eliminated. After the leakage protector is put into operation, every time after a period of time, the user should check whether the circuit breaker is running normally through the test button.

  3. ambient air temperature does not exceed the ceiling 40 C, the lower limit of not less than -25 DEG C, and the average temperature within 24 hours of not more than +35 DEG C.

Product specification

Working principle of product

   A small circuit breaker is the principle that the bimetal bending is directed regularly with the increase of temperature. When the circuit breaker is closed in normal working condition, the internal bimetallic sheet is heated by a certain current, and the thermal expansion coefficient of the two bimetalles is different. It is not enough to release the release mechanism. When the line appears general overload, when the overload current is reached, the bimetallic sheet has a larger bending angle and a lever in the release mechanism, which is enough to push off the release mechanism, and from the small circuit breaker, it plays the role of super load protection. The size of the bimetallic strip is different from that of the small circuit breaker.
