The difference between isolating switch and circuit breaker: The full name of air switch is air-type low-voltage circuit breaker, which is a type of circuit breaker mainly used in low-voltage circuits. Because it uses air as the medium for arc extinguishing, it is called an air-type low -voltage circuit breaker, or air switch for short. The power distribution in the buildings at our homes is basically air switches. The isolating switch is a high-voltage switching appliance mainly used in high-voltage circuits. It is a switching device without an arc extinguishing device. It is mainly used to disconnect circuits with no load current and isolate the power supply. There is an obvious disconnection in the open state. points to ensure the safe maintenance of other electrical equipment. In the closing state, it can reliably pass normal load current and short-circuit fault current. Because it does not have a special arc extinguishing device, it cannot cut off the load current and short-circuit current. Therefore, the isolation switch can only be operated when the circuit has been disconnected by the circuit breaker. with load is strictly prohibited to avoid serious equipment and personal accidents. Only voltage transformers, arresters, no-load transformers with excitation current not exceeding 2A, and no-load lines with current not exceeding 5A can be directly operated by isolating switches. In electric power applications, circuit breakers are mostly used in conjunction with isolating switches. Circuit breakers are used to switch on and off load (fault) currents, and isolating switches are used to form obvious disconnection points. Feature: *The isolation switch is a switching device mainly used for "isolating power supply, switching , connecting and cutting off small current circuits" and without arc extinguishing function. *Red and green visualization : operating status is clear at a glance to avoid mis *Fire-proof and flame-retardant: safe insulation, overall flame-retardant, strong environmental adaptability, meeting application needs in various occasions, and reliable even in harsh environments. * Fastening guide rail, buckle design: Tight buckle, firmly blocking the guide rail, you can also use screws to fix the installation. *Used in a variety of places: Isolating switches are mostly used in engineering construction, hotels, homes, offices, schools, shopping malls, etc. Specification: Product name: Isolating switch Product level: 2P Product model: HL30-125 series Rated voltage: 400V Rated current: 32A/63A/80A/100A Frame current: 63A Rated frequency: 50/60Hz Wire entry : top in and bottom out Product size: 36*81*76mm Product weight: 0.118kg Package Contents: 1*Isolating switch Note: 1.
