When a short circuit occurs in the electrical circuit, the current in the protected line exceeds the rated current, the line voltage is over or under voltage, or a fault arc occurs, and the cable temperature is too high, traditional circuit breakers, switches, and monitoring devices cannot detect the fault arc or the fault, fail to quickly trip the power supply, and are prone to fires and have a short service life.
In response to these existing safety concerns, our R&D team has developed a new type of online electrical fire-limiting protection device—the electrical fire-limiting protector/smart electrical usage protector. In the event of a short circuit fault, it can rapidly limit the short-circuit current at a microsecond speed to ensure electrical safety, significantly reducing the occurrence of electrical fires and safeguarding the safety and property of personnel and users in the facility.
