Siemens 3TF series AC contactor our company; low-voltage electrical appliances, AC contactors, industrial plugs, instrumentation, high and low voltage equipment operators, Siemens, ABB, Schneider, Korea LS, Omron, Fujitsu electromechanical, Hang On. Cade Siemens AC contactor, 2015 latest offer one of the series AC contactor is mainly used in AC 50Hz or 60Hz, rated insulation voltage of 660V - 1000V, rated work in AC-3 using the category rated voltage of 380V operating current of AC contactor Siemens 9A - 400A power lines. Primarily for long-distance making and breaking the circuit, and for control of AC motor starting, stopping and reversing. Product complies with IEC60947-4-1, GB14048.4 standards. Second, the use of environmental conditions 1. Ambient temperature: -25 ℃ - + 55 ℃; 2. Relative humidity: at + 40 ℃ does not exceed 50%; at a lower temperature allows a higher relative humidity; 3. Altitude: not exceed 2000m; 5. Installed in the absence of a significant shake and shock vibration place; 6. Installed without rain and snow; 7. Change control voltage range: 0.8 - Third, the structural characteristics 1. The overall structure: double-break contacts for direct-acting contact sports institutions, with three pairs of normally open main contacts, auxiliary Hoon may have two normally open contacts, two normally closed. Contactor contact support member and the armature elastic coupling lock and eliminate weaknesses. Action mechanism and flexible, easy to manually check, compact design prevents debris and dust fall outside activity area, the terminal has a defense cover staff not directly contact with live parts. Contactor compact dimensions, small mounting area. Mounting rail mounting available, can also be used screws robust compared with other similar products, higher operating frequency and control capacity. Good safety performance, conductive parts are not exposed; product safety, reliability, advanced international contacts. 2. Contact system: primary, secondary electrical contact material by the superior performance of silver alloy, has a long life and good contact reliability. Interrupter was closed, and a fire-retardant material blocking outward arc spray, le≤22A without extinguishing the arc across the board, le≥32A with metal arc across the board, to ensure personal and close to electrical safety. The new Terminal screw jack screw, tile-shaped pad with screw terminal with no separation can save time. 3. Magnetic Systems: solenoid reliable, low loss, low noise, and having a high mechanical strength, high operating frequency and control capacity, the terminals are equipped with a voltage specification chart marker cards, nameplates coated with a specific voltage levels color, clearly visible wiring convenience, you can avoid a wrong voltage specifications lead to coil burnt. Small size, light weight, arc chute materials used unsaturated resin, arc resistance, and will not break; interrupter was closed, arcing from the small, can reduce the size of the electrical box; main contact system unique structure , contact wear small, increase the electrical life; (CCC), Siemens (SIEMENS) AC Siemens (SIEMENS) Contactor Selection Guide (CCC), Siemens (SIEMENS) AC Siemens (SIEMENS) function contact information (CCC), Siemens (SIEMENS) AC Siemens (SIEMENS) contactor Manual Price (CCC), Siemens (SIEMENS) AC Siemens (SIEMENS) contactors offer description Agency We are a professional agent Siemens (SIEMENS) Siemens, welcome customers throughout the country, to purchase, wholesale.
