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
