Contactor KTI-7630 630A 400V/AC3

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: 400 Rated control supply voltage Us at DC: - Rated operation current Ie , 400 V: 630 Connection type auxiliary circuit: EV000415 Number of auxiliary contacts as normally closed contact: 0 Number of auxiliary contacts as normally open contact: 1 Nominal operating AC voltage Ue: 230; 400; 660 Rated insulation voltage Ui: 1000 Rated surge voltage: 8 Conditional heat current Ith at AC-1: 1000 Nominal powet at AC-3 230V: 200.0 Nominal powet at AC-3 400V: 335.0 Nominal powet at AC-3 660V: 450.0 Max short-term load: 5040 Conventional Short Circuit Current Inc: 18000 Ov
