Vacuum contactor AC-3e 630 A, 335 kW / 400 V, AC-3 820 A, 450 kW / 400 V, Ue 690V, 3-pole, Uc: 24 V DC Drive: conventional with series resistor built in with changeover contactor 3TC4417-4A DC economy circuit Auxiliary contacts 3 NO + 3 NC Main circuit: rail Control and auxiliary circuit: screw connection Vacuum contactor 3TF6 for switching motors. The 3TF6 vacuum contactors impress with their maximum performance combined with a compact design and high contact reliability. They are also characterized by a particularly long switching life. They are therefore particularly suitable for frequent switching in inching mode. Pre-assembled auxiliary switches reduce the complexity of your setup. The devices are approved worldwide (eg IEC and UL/CSA) and IE3/IE4 ready. They are available in two sizes, in AC or DC operation and in a wide power range. In the main circuit, the devices can be connected via rails. There are a wide range of accessories for these contactors, such as surge suppressors, auxiliary switches or terminal covers.
