The circuit breaker should fully consider the actual situation of electricity consumption
Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise and residential buildings, and their safety cannot be ignored. Recently, the Provincial Quality Supervision Bureau organized and carried out the province’s small circuit breaker product supervision and inspection, and randomly inspected 8 batches of products from 8 small circuit breaker enterprises. All products in this random inspection are qualified.
Miniature circuit breakers are maintenance-free switching electrical products, which can protect electrical appliances and distribution lines from over-current and short-circuit, and can also protect against fire accidents caused by overheating of lines. The Provincial Bureau of Quality Supervision reminded that the price of small circuit breaker products ranges from a few yuan to dozens of yuan depending on the quality.
Therefore, users must choose suitable products according to their actual electricity consumption. For example, when the capacity of the power supply transformer is large or the transmission line is short, a product with a higher breaking capacity should be selected, because if the small circuit breaker cannot effectively break the short-circuit current, it will catch fire and burn.
It is easy to cause fire accidents; for end protection products, small circuit breakers with two poles should be selected as far as possible; in addition, more advanced products with a certain well-known brand should be selected as far as possible.
