Overview of over voltage protection
Over voltage protection device is a commonly used protection device in the market. In particular, in the city of large fluctuations in the power of the site, a variety of electrical equipment and appliances can be used to protect the protection, so that the use of electrical equipment and home appliances to avoid damage in the condition of abnormal voltage. When the voltage of the city is over or below the protection action voltage, the protector can quickly and reliably cut off the power supply, so as to protect the power equipment, such as the power voltage recovery, the protector can automatically connect to the power source (usually 2min delay protection), use the power equipment to restore power supply, automatic protection control.
Work protection features: the use of dual color light emitting diode to indicate the working status of the protection device, the indicator light is green when the normal power supply; red when the protection functions (over voltage or under voltage protection) start, power supply has been cut off. In the protection of the power of the device, because of the protection of the internal use of high power electromagnetic relay, the contact allows the larger current (usually up to 20A resistance), it can be used to protect the power of large power equipment (4.4kW). In the installation and use, the product structure is compact and reasonable, can be used with the small circuit breaker and installed in the C45 guide, the use of the power distribution box, to the installation and use are more convenient.
