1. Che cos'è un picco? Un picco è una sovratensione transitoria che supera la normale tensione operativa. 2. Cos'è un protezione contro le sovratensioni? A protezione contro le sovratensioni is an electronic system that, when a circuit or communication network suddenly generates peak current or overvoltage due to external influences, it can be cut off and disconnected in a very short time to avoid damage to other equipment in the circuit by the surge. 3. What is the difference between a switching protezione contro le sovratensioni and a voltage limiting protezione contro le sovratensioni? The switching protezione contro le sovratensioni is a gap discharge device, and the lightning energy is large. The key role of the route is to release the lightning energy; the voltage limiting protezione contro le sovratensioni is a zinc oxide varistor device, which has low lightning energy but good overvoltage suppression capability. The key to use is to limit overvoltage. Therefore, it is usually used in building entrances, such as Asafe series of switching surge protection to release lightning energy, and then, in subsequent circuit applications, such as AM series of voltage limiting protezione contro le sovratensionis to limit the former lightning energy after the drop Subsequent routes generate high overvoltages. Both types of protezione contro le sovratensionis should be used together to ensure the safety of equipment in distribution lines. 4. How to choose a miniature circuit breaker with a protezione contro le sovratensioni? Asafe cannot install a miniature circuit breaker because the damage method of the switch module is to lead the way; the first-level module, such as the first-level module, such as AMI-40, must use a 63A breaking current capacity of 10KAD type miniature circuit breaker; the second-level module, such as AM32- 20 must use A C.D with a breaking current capacity of 6.5KA. Due to its working curve, the miniature circuit breaker IN is recommended to use D type; third-level modules, such as third-level modules, such as AM16-10 must use A breaking current capacity The C.D working curve of the 4.5KA miniature circuit breaker IN has different values, so it is recommended to use the D type. 5. Is a fuse device installed in front of each protezione contro le sovratensioni? no. Since the damage method of the switch module is to lead the way, there is no need to install fusing devices such as miniature circuit breakers.
