household electrical leakage open circuit protection DZ47 small circuit breaker household air switch.
Brief introduction
DZ47 series small circuit breaker is a kind of limited current high
breaking small circuit breaker with double protection of overload
and short circuit. It is mainly used for overload and short circuit
protection of electrical lines and equipment in modern buildings,
and is also suitable for infrequent operation and isolation of
lines.
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 relative humidity of the atmosphere is less than 50% when
ambient air temperature is + 40 C, and the relative humidity can be
allowed at lower temperature.
2. installation place: the external magnetic field of the
installation site should not exceed 5 times of the earth's magnetic
field in any direction.
3. where there should be no significant vibration and shock at the
installation
