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.
Use of attention
1. the insulation resistance between the pole and pole
(except the monopole), the end and the outlet end of the circuit
breaker should be not less than 2M Omega, and the insulation
resistance between the pole and the shell, the pole and the
installation rail should not be less than 5M Omega. If the product
is not required, the product shall not be used and should be
exchanged in time with the supplier.
2. the setting temperature of the series circuit breaker is
30 +5 C. If a number of circuit breakers are loaded into the sealed
box at the same time, the temperature of the box is raised
correspondingly, and the current is 0.8In.
3. the circuit breaker needs to check contacts after
the circuit is short circuited. If the main contact burns seriously
or has pits, it needs to be repaired.
