SJK47-63 3P miniature circuit breaker

Scope of application
The SJK47-63 miniature circuit breaker has the characteristics of advanced and reasonable structure, reliable performance, high breaking capacity, and beautiful and compact appearance. The shell and other components are made of impact resistant and highly flame-retardant materials. Suitable for AC 50Hz or 60Hz, rated voltage 220/380V, rated current up to 63A line. It is mainly used for overload and short circuit protection of lighting, distribution lines, and equipment in various places such as industrial, commercial, high-rise office buildings, and residential buildings. It can also be used for infrequent operation and conversion of lines under normal circumstances
Compliant with standards: GB10963.1, IEC60898-1, and obtained CCC certification

Main parameters and technical performance
◆ Main specifications
◇ Divided by rated current In: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A
According to the type of instantaneous release, it can be divided into: C-type (5-10) In D-type (10-14) ln
◇ Divided by pole: a. Single pole circuit breaker
b. Circuit breaker with three protective poles
c. Circuit breaker with four protective poles


Other
◆ Structural Features
◇ Composed of plastic casing, operating mechanism, contact arc extinguishing system, tripping mechanism, etc
The shell is made of special plastic with high flame retardancy, high temperature resistance, and high strength, which has strong impact resistance and light weight
The components of the circuit breaker operating mechanism are made of high-strength plastic products, which ensure sensitivity and reliability while obtaining the lowest moment of inertia, making the time from the beginning of the short circuit fault to the action of the trip mechanism very short
The trip mechanism consists of two parts: a bimetallic overload inverse time trip mechanism and a short-circuit instantaneous electromagnetic mechanism
The contact arc extinguishing system adopts special arc angles and arc extinguishing chambers, which have significant current limiting characteristics
◇ Applicable working conditions and working environment:
a. Environmental temperature: -25 ° C~+60 ° C. When the environmental temperature is not the benchmark of 30 ° C, please refer to Table 6 for coefficient correction

b. Altitude: The altitude of the installation site shall not exceed 2000m
c. Installation method: TH35-75 steel installation rail is used for installation
◇ With isolation function
