GT-A25 a power surge protector (SPD National Recruitment Agents)
Shanghai Gan Tai Electric Co., GT series surge protector National Recruitment agents, QQ: 3151011, Mobile: 18968928968, 15381518630 ??First, the scope: GT series surge protectors for the power grid voltage 1000V following, frequency 48 / 62Hz for a variety of low-voltage distribution systems. Such as telecommunications, railways, banking system, oil, high-rise buildings, homes, offices and other distribution systems. These power units with electrical appliances (such as computers, equipment, household appliances, etc.) from lightning, transient over-voltage surge overvoltage damage caused. Ensure that equipment and personal safety. Is ideal for over-voltage protection devices. Second, the main structure and working principle: In the three-phase five-wire system, the three-phase line and a neutral ground between both protector. Under normal circumstances, the protection is in a high impedance state, when the grid due to lightning or other causes over-voltage surge protector will promptly turned over nanosecond time, the surge voltage into the earth, thereby protecting the electrical electrical equipment online. When the over-voltage surge protector and disappeared through the protector again restored to a high-impedance state. So as not to affect the normal operation of the grid. Three characteristics: 1, using internal wiring, the overall structure is compact, easy to install. 2, high-speed response, the operating time of less than 25ns. 3, work status display clear, green (normal), red (fault). 4, additional features, such as R: hot backup; C: counter; Y: telesignalling four, GT's normal operating conditions 1, altitude less than 2000m; 2, ambient air temperature: the normal range: -10 ℃ ~ + 40 ℃ limits: -40 ℃ ~ + 70 ℃ 3, relative humidity: at room temperature for 30% to 90%; 4, and the vertical angle of inclination of not more than 5 °; 5, no significant shake and shock vibration place; 6, no explosive medium, the medium does not enough to corrode metal and damage the insulation of gas and dust (including conductive dust). Fifth, the technical parameters Model Specification Test category Uc (V) In (KA) Imax (KA) limp (KA) Up (KV) Dimensions Length X Width X Height (mm) GT-D20 / 385V / 4P II Class 38510 20 / <1.5 90X72X65 GT-C40 / 385V / 4P II Class 385 20 40 / <1.8 90X72X65 GT-B60 / 385V / 4P II Class 385 30 60 / <2.0 90X72X65 GT-B80 / 385V / 4P II Class 3854080 / <2.2 90X108X65 GT-B100 / 385V / 4P II class 385 60 100 / <2.5 90X144X65 GT-B150 / 385V / 4P II class 385 80 150 / <3.0 90X144X65 GT-A25 / 275V / 4P Class I 275 25/25 <2.0 100X144X65 GT-A50 / 275V / 4P I grade 275 50/50 <2.0 100X144X65
