small circuit breaker breaker DZ47 short-circuit protector for household total open air switch
Brief introduction
The DZ47 circuit breaker, or the small circuit
breaker, is one of the plastic case circuit breakers. It is the
most widely used terminal protection device in building electrical
terminal distribution device. For single phase and three phase
short circuit, overload, overvoltage protection and other
protection under 125A, it includes four kinds of monopolar 1P,
bipolar 2P, three pole 3P and quadrupole 4P.
Use of attention
1. There should be no significant vibration and shock at the .
installation.
2. check whether the technical parameters on the pad are in line
with the requirements.
3. 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.

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.
