Brief introduction
JGXL-63S three-phase four-wire current-limiting over-undervoltage protector is mainly used for AC 50Hz (60Hz), rated working voltage 220/380V, main rated current from 2A to 63A, intelligent controller adjustable working current from 2A to 63A, control power from .5KW to 20KW in the power system switched on, carrying and breaking the current or voltage under normal conditions (including the specified overload conditions), and can also be turned on, carried and carried for a certain time and under the specified abnormal conditions (such as short circuit). , undervoltage, etc.).
The three-phase four-wire current-limiting over- and under-voltage protector adopts a modular product structure type, which has the advantages of small size, high reliability and convenient operation. The main functions of the product are: overvoltage, undervoltage, phase failure, zero line and zero line, overcurrent, instantaneous short circuit, three-phase unbalance, undercurrent, phase sequence, RS485 communication, one-key factory reset and other functions, which are widely used in: telecommunications, metallurgy, coal mines, steel, petrochemical, ports, ships, railways, hospitals, intelligent buildings and other fields of power distribution and motor protection control systems.
Main technical parameters:
1. Voltage detection range: AC80~450V, accuracy level: 1.0.
2. Current detection range: 1~63A, accuracy level: 1.0.
3. The power consumption of the product itself: ≤2W.
4. Withstand short-circuit current: 2000A.
5. The mechanical life ≥ 100,000 times, and the electrical life is 5,000 times.
6. Product wiring method: down and down the line outlet, up in and out of the line. The default wiring method is the bottom line and the outgoing line.
7. The wiring capacity is 16 square meters.
8. For details of RS485 communication protocol, please refer to “RS485 Communication Manual V2.0 for Power Meters and Protectors”.
