Contactor, size 12, 2-pole, DC-4, nominal operating current 400A auxiliary switch 4NO+4NC DC 110V with integrated varistor DC operation DC operation contactor 3TC for switching direct current, 2-pole.The 3TC direct current contactors impress with their maximum performance and compact design and high contact reliability. They are also characterized by a particularly long switching life. Pre-assembled auxiliary switches reduce the complexity of your setup. The devices are approved worldwide (e.g. IEC and UL/CSA).They are available in different sizes, in AC and DC operation, in different voltages and with different auxiliary contacts. 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.
