Descriere produs

Electromagnetic contactors of KTIe 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.High switching endurance.Low noise.Economical solution.Simplicity of design.Rated control supply voltage Us at AC 50HZ: 230Rated control supply voltage Us at DC: -Rated operation current Ie , 400 V: 170Connection type auxiliary circuit: EV000415Number of auxiliary contacts as normally closed contact: 0Number of auxiliary contacts as normally open contact: 0Nominal operating AC voltage Ue: 230…400Rated insulation voltage Ui: 1000Rated surge voltage: 8Conditional heat current Ith at AC-1: 200Nominal powet at AC-3 230V: 45.0Nominal powet at AC-3 400V: 90.0Max short-term load: 1400Conventional Short Circuit Current Inc: 10000Overcurrent Protection – Fuse gG: 250Dissipation power at Ie AC-3: 13,5Dissipation power at Ie AC-1: 24Tightening moment: 6Screw diameter metrical: 8Control voltage ranges at actuation Uc: 0,85…1,1Flexible cable without tip: 95…150Control voltage ranges at release Uc: 0,3…0,5Hard cable without tip: 95…150Closing Response Time: 20…35Response time at opening: 40…75Switching wear and tear during AC-3: 0,6Mechanical wear resistance: 0.7Ambient temperature: -45…+55Width: 120.0Height: 158.0Voltage 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: 120
