Contactor size 14, 3-pole, AC-3, 450 kW, 400/380 V (690 V) (4 NO + 4 NC)

КОНТАКТОР ТИПОРАЗМЕР 14, 3-ПОЛЮСА AC-3, 450КВТ, 400/380V (690V) ДОПОЛНИТЕЛЬНЫЕ КОНТАКТЫ 44 (4НO+4НЗ) УПРАВЛЕНИЕ ПЕРЕМЕННЫМ ТОКОМ AC 230 ДO 276V 50/60ГЦ Vacuum contactor 3TF6 for switching motors. The 3TF6 vacuum contactors offer convincing high performance from a compact design with high contact reliability. They are also characterized by their particularly long switching endurance. They are therefore particularly well suited to frequent switching in inching operation. Pre-installed auxiliary switches reduce the complexity of your design. The devices are approved for worldwide use (e.g. IEC and UL/CSA) and are IE3/IE4-ready. They are available in two sizes, with AC and DC operation, and in a wide performance range. The devices can be connected in the main circuit by means of rails. A wide range of accessories is available for these contactors, such as surge suppressors, auxiliary switches or terminal covers.
