Parameter detection of circuit breakers for narrow gauge industrial and mining electric locomotivesHow to apply for a report? What items need to be tested? We will conduct testing and evaluation in strict accordance with the standards. We can also provide personalized testing plans and reports according to your needs.

A circuit breaker refers to a switching device that can close, carry, and break current under normal or abnormal circuit conditions. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague, and generally, those above 3kV are referred to as high-voltage breakers. According to the operation mode, there are electric operation, energy storage operation, and manual operation; According to structure: there are universal and plastic shell types; Classified by usage category: selective and non selective; According to the arc extinguishing medium, there are oil immersed, sulfur hexafluoride, vacuum type, and air type; According to movement speed: there are fast and regular types; According to the number of poles: there are single pole, two pole, three pole, and four pole, etc; According to installation methods, there are plug-in, fixed, and drawer types
