Automatic transfer switch SGLD (general type):General:SGLD series automatic transfer switch suitable for AC50HZ ,rated voltage 380V, DC rated voltage up 220V,rated electric current to 3200A.The switch is used in the infrequent on and off circuit.Performance characteristics: 1.Full electrical engineering integrity which allows auto-control without external controller 2.The world high-tech logic control circuit with strong anti-jamming and no environmental interference. 3. The mechanism with spring powered accumulator applied in the switch main body, which allows for zero electrical arc by the feeler connection and disconnection. 4. The products have three poles, four poles , and (three poles + on and off neural pole) 5. Current grades can be divided into 100A160A250A630A1000A1250A1600A.2000A2500A3200A 6. 3 control modes(RBC) 7. R. Municipal power supply- Municipal power supply, automatic change and automatic recovery, protection of missed phase. 8. B. 125A up to 630A Municipal power supply-Municipal power supply, automatic change and automatic recovery, over voltage or lower-voltage function. 9. C. Municipal power supply-oil generator, automatic change and automatic recovery. Having the functions of over-voltage or lower-voltage of phase shortage protection and frequency detection.10. The switches can be padlocked to keep the position status 11. To use key to switch to select operation.Rated current Ith20A40A60A80A100A125A160A250A400A630A800A1000A1250A1600A2000A2500A3200ARated insulation voltage Ui750V1000VRated concussion withstand voltage Uimp8000V1200VRated working voltage UeAC440VRated working current IeAC-31A20106380100125160250400630800100012501600200025003200AC-35A20106380100125160250400630800100010001250200020002500AC-33A20106380100125160250400630800100010001000125012501250Rated connection ability10 IeRated disjunction ability8 IeRated limit short power100KA70KA100KA120KA80KATransfer time I-II or II-I0.45S0.65S1.25S2.45SControl power voltage7KV9KV13KV50KV55KVElectrical consumptionDC24V, 48V, 110V, AC220VRated control voltagestart300W325W355W400W440W600Wnormal55W62W62W90W98W120WWeight7.07.27.27.27.57.58916.517323640499598135
