Descriere

Descriere produs

Electromagnetic contactors of KTI series are intended for use in control circuits for start and stoppage of 3-phase squirrel-cage induction motors supplied from mains with rated voltage up to 660 V, and also can be used for switching on/off other electrical units: lighting, heating devices, various inductive loads. Used with fans, pumps, furnaces, beam cranes and automatic load transfer systems.Simple design provides for easy maintenance of components.The base is made from aluminum shape that ensures increased robustness and lesser weight compared with similar designs.Wide range of optional devices readily available in the stock (PKI contact attachments, PVI time-delay attachments).Broadened range of offered KTI electromagnetic contactors as compared to the similar products from domestic manufacturers on Russian market.Rated control supply voltage Us at AC 50HZ: 400Rated control supply voltage Us at DC: -Rated operation current Ie , 400 V: 115Connection type auxiliary circuit: EV000415Number of auxiliary contacts as normally closed contact: 0Number of auxiliary contacts as normally open contact: 1Nominal operating AC voltage Ue: 230; 400; 660Rated insulation voltage Ui: 1000Rated surge voltage: 8Conditional heat current Ith at AC-1: 200Nominal powet at AC-3 230V: 30.0Nominal powet at AC-3 400V: 55.0Nominal powet at AC-3 660V: 80.0Max short-term load: 900Conventional Short Circuit Current Inc: 5000Overcurrent Protection – Fuse gG: 200Dissipation power at Ie AC-3: 5Dissipation power at Ie AC-1: 15Tightening moment: 10Double bus – each size: 20х3Screw diameter metrical: 6Control voltage ranges at actuation Uc: 0,8…1,1Control voltage ranges at release Uc: 0,35……0,55Closing Response Time: 23…35Response time at opening: 5…15Switching wear and tear during AC-1: 0,5Switching wear and tear during AC-3: 0,8Section of wire with tip: 95Flexible cable 1 or 2 wires: 1…4Mechanical wear resistance: 1.0Flexible cable with 1wire tip: 1…4Flexible cable with 2 wires tip: 1…1,25Hard cable without tilt 1 or 2 wires: 1…4Number of additional contacts: 1Ambient temperature: -45…+55Width: 163.5Height: 162.0Additional terminal – Nominal voltage Un AC: ≤ 660Additional terminal – Nominal insulation voltage Ui: 660Additional terminal – Thermal resistance current In: 10Additional terminal – Overcurrent protection – pre-ocher gG: 10Additional terminal – Max short-term load: 100Additional terminal – Insulation resistance: > 10Voltage type for actuating: EV000460Number of auxiliary contacts as normally closed contact, delayed switching: 0Number of auxiliary contacts as normally open contact, leading: 0Number of auxiliary contacts as change-over contact: 0Number of poles: 3Repeated-short mode: 120Additional terminal – Tightening torque: 1.2
