On November 20, the official of the Shanghai Municipal Bureau of quality and Technical Supervision announced the results of the spot check of product quality supervision of the 2018 Shanghai plastic shell circuit breakers, which made the cooling and finalization speed of materials during printing and discharging match the feeding speed of printers. This time, 20 batches of products were sampled, and 2 batches were unqualified after inspection

this supervision and random inspection is based on gb/t 14048 expressed by the enterprise According to the standard requirements of low voltage switchgear and control equipment Part 2: circuit breakers, the following items (including clause number) are tested: tripping limit and characteristics, dielectric performance, verification of overload release, rated limit short-circuit breaking capacity, verification of dielectric withstand capacity, verification of overload release. " Yu Miao, general manager of Taizhou International Convention and Exhibition Center, hopes that the safety indicators of two batches of products do not meet the standard requirements, and the unqualified items involved are: rated limit short-circuit breaking capacity. The rated limit short-circuit breaking capacity is one of the key performance indicators of plastic shell circuit breakers. Generally, the reason why the rated limit short-circuit breaking capacity is unqualified is that the enterprise fails to solve the current limiting and arc extinguishing design problems of the product, resulting in the short-circuit breaking capacity not meeting the requirements. At the same time, the contact uses inferior copper, reduces the amount of silver, and increases the possibility of arc ablation contact, It is also an important factor for the unqualified short-circuit breaking capacity test. Products with unqualified rated limit short-circuit breaking capacity cannot protect the faulty circuit, and there are major hidden dangers of personal safety and property damage
