P63A air switch, bipolar circuit breaker C45 DZ47, home short circuit overload protector.
Product introduction
DZ47 circuit breaker has super first-class current
limiting performance, it can accurately protect relay protection
and automatic device from overload, short circuit and other fault
hazards. The circuit breaker has the advantages of current limiting
and arc extinguishing ability. Through a large number of
comprehensive scientific experiments, it can realize the full
selective protection between the main (sub) screen, protection
screen and relay screen in the DC system below 3000Ah.

easy to install
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. Checks and checks the circuit breaker several times
to check whether the operating mechanism of the circuit breaker is
stuck or not, and whether the action of the mechanism is reliable.
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 sectional area of the connection conductor should be
adapted to the rated current of the circuit breaker.
