High-voltage reed relays can be classified according to their rated voltage, current, switching capacity and other parameters. Here are some common ways to categorize: Voltage ratings: High voltage reed relays are typically rated between thousands of volts and hundreds of thousands of volts. According to the different rated voltage, the high-voltage reed relay can be divided into different models, such as 1 kV, 3 kV, 7.2 kV, 10 kV, 20 kV, etc. Rated current: The rated current of high voltage reed relay is usually between several hundred amperes and several thousand amperes. According to the different rated current, the high-voltage reed relay can be divided into different models, such as 200A, 400A, 630A, 800A, 1000A, etc. Switching capacity: The switching capacity of a high-voltage reed relay usually refers to the product of its rated load current and rated breaking voltage. According to different switch capacities, high-voltage reed relays can be divided into different models, such as 5kV/200A, 10kV/400A, 15kV/800A, 20kV/1000A, etc. Features: According to the different features of high voltage reed relay, it can also be divided into different models, such as high voltage reed relay with time delay function, high voltage reed relay with overvoltage protection function, etc. In a word, there are many ways to classify high-voltage reed relays, and the appropriate model can be selected according to the specific application requirements.
