220V surge arrester for household appliances, 4P 80KATRS9-B80 protector.
Product introduction
Surge protector is a lightning protection measure adopted by Zhejiang toer Electric Co., Ltd., which is independently developed and produced for electrical system. Its core components are composed of multistage graphite gap. Reasonable design and precise processing of spark and twisting together form a sealing mechanism to ensure the safety distance of spark gap, even in surge current. When it passes through, there will not be any arc leakage. It will effectively protect the device against surge and over voltage.
Working principle of product
The working principle of surge protector is a high resistance open state with a low voltage, low resistance and short circuit state at high pressure, and a combination of over voltage protection electronic devices which can withstand hundreds of amperes and large current in parallel on the power supply line and signal transmission line. When encountering lightning and high voltage and high current, it will appear short circuit immediately, and at the same time, the total power switch will be disconnected, so that the device will be protected.
Product specification
1. Rated Operating Voitage(UC):275V
2. Voltage protective level(UP):1.7KV
3. Max discharge current(IMAX):80KA
4. Nominal discharge current(IN):40KA
5. Ressponse time(NS):<25
Product features
1. self protection voltage is more than self protection, automatic disconnection and recovery.
2. with the power status indication, indicating the working state of surge protector
.
3. alarm indicating device, normal (green), red (fault).
Notice of product
1. in order to avoid unnecessary induction loops, we should mark the PE conductor of each device.
2. data line: more than 2.5mm2; when the length of more than 0.5 meters of more than 4mm2
3. generally speaking, it is better to separate the protected conductor from the non protected conductor, and it should be separated from the ground wire. At the same time, in order to avoid transient orthogonal coupling between power cables and communication cables, necessary measurements should be made.
