Description
Dz****3 miniature circuit breaker (DZ*7 air switch) is mainly
suitable for AC *0 / *0Hz with rated working voltage of **0 and
below, rated current up to *3A.The circuit breaker is mainly used
in modern construction. The overload and short circuit protection
of electrical circuits and equipment of buildings is also
applicable to infrequent operation and isolation of lines.
Structural characteristics
The circuit breaker is composed of plastic shell, operating
mechanism, contact arc extinguishing system, and disconnection. It
is composed of buckle mechanism, etc. The shell is made of special
plastics with high flame retardant and high strength can Light
weight.
The parts of the mechanism are made of high strength plastic
products to ensure sensitivity
The time from the start of short circuit fault to the action of
tripping mechanism is very short. The trip mechanism consists of
bimetal overload inverse time release mechanism and short circuit
instantaneous electromagnetic mechanism form.
The arc system adopts special guide arc angle and passage chamber,
and has remarkable current limiting characteristics. It is mainly
used for lighting, power distribution lines and equipment overload
and short circuit protection of office buildings, residential
buildings and similar buildings
Usually, it is used for infrequent line conversion.
The product meets the requirements of c****8 and gb****3.1
