Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is a moulded case circuit breaker, which is a low-voltage electrical protection device with all components sealed in a plastic case, with a single-unit weight of about 7.582 kg, a rated insulation voltage of 800 V and a rated working voltage of 400 V, mainly made from copper and iron fittings, wires, and purchased electronic components and plastic fittings, etc., through processes such as welding, assembly and testing. The key upstream raw materials of this product are components such as copper and iron fittings, wires, electronic components and plastic fittings, and downstream it is mainly applied in the control and protection of power systems and branch circuits. In terms of system boundary, the packaging of the product and the transport, use, scrapping, recycling and final disposal after leaving the factory, as well as infrastructure such as the manufacture of production equipment and the construction of plant buildings, are not included within the dataset boundary. In terms of data sources and data processing, the data inventory is taken from the actual data of Chinese production enterprises and merged.
Activity Description
The system boundary for the molded case circuit breaker is defined as cradle-to-gate, covering from raw material input to finished product dispatch. The main process stages, in sequence, include welding (of copper/iron components and leads), assembly (of electronic components and plastic parts), and testing.
Process Description
Circuit breaker refers to a mechanical switching appliance that can connect, carry and break current under normal circuit conditions, and can also connect, carry and break current under specified abnormal circuits (such as short circuits) for a certain period of time. It is mainly divided into air circuit breakers, vacuum circuit breakers, SF6 circuit breakers and plastic case circuit breakers. Plastic case circuit breaker is a kind of low-voltage electrical protection equipment. All components are sealed in a plastic case. It usually has a modular design and is mainly composed of copper and iron accessories, wires, electronic components and plastic cases. It has strong short-circuit breaking capacity, overload, short-circuit and under-voltage protection. The current level ranges from 6 amps to 1250 amps. It is in the form of cabinet-mounted or bench-mounted switchgear. It is widely used in the control and protection of power systems and branch circuits.

Technology comment
The production of molded case circuit breakers mainly includes processes such as welding, assembly, and testing. After surface soldering of copper and iron accessories and wires, they are assembled on the production line with purchased components such as electronic elements and plastic parts. After passing a series of tests including temperature resistance, voltage withstand, and dielectric tests, the finished molded case circuit breaker is obtained.
