Application
TK400D 24V/400A DC Contactor High Voltage is used to control the current flow in the power system to realize line switching, protection, and control. It plays a key role in power transmission and distribution stations and substations to ensure the stable operation of the power grid.
Ordering Notice
For example: TK400D/12V
The DC contactor of main contact is one NO, rated voltage not more than DC 96V, current 400A, coil
