The circuit breaker, as the name suggests is a kind of automatic switch can cut off the circuit, it is both a manual, also can automatically wire cable, lighting equipment and motor overload, short circuit protection appliances, can also be used as a line without frequent conversion by. When the electrical equipment has serious overload or short circuit, it can automatically cut off the circuit. The breaker does not need to replace parts after breaking the current, so it has been widely used. Handsome electrical safety electrical professional production for more than 20 years, tired actively its rich technical experience, has independently developed the quality and stability of the miniature circuit breakers and leakage breaker.
Installation of JUNON miniature circuit breaker:
1, under normal circumstances, the circuit breaker should be vertical installation and vertical surface, the slope is not more than + 5 degrees.
2, the installation should pay attention to the following:
(1) check whether the mark of the breaker is in conformity with the normal working conditions used;
(2) the circuit breaker shall be installed vertically so that the handle is facing downwards;
(3) when the circuit breaker is installed, attention shall be paid to the sign at the terminals.
3. The magnetic field outside the installation shall not exceed 5 times of the magnetic field in any direction, and the installation shall be free of significant shock and vibration.
Application and maintenance of JUNON miniature leakage circuit breaker:
1. To close the circuit breaker, push the handle upward in the direction of the ON arrow. To break it, pull the handle downward in the direction of the OFF arrow.
2, leakage circuit breaker in a certain period of time (usually run for a month, need to pass the test button) press the power state in the closed, check whether the normal operation of the leakage protection performance (each time you press the test button, average leakage breaker broken once).
Precautions for using JUNON small earth leakage circuit breakers:
1, leakage circuit breaker in the transportation, storage and use of the process, shall not be affected by rain and snow;
2 、 the leakage circuit breaker after assembly can not protect the electric shock caused by the contact of the two wire of the protective circuit;
3. After installation, the leakage circuit breaker shall be used in the use of the circuit breaker, and the relative reduction factor is 0.8 relative to the breaker.
4, do not use electronic electric leakage breaker tramegger insulation.
