The Schaltbau CT series stands for single and double pole NO contactors for AC and DC (bidirectional) with a rated insulation voltage of up to 4800 volts and a continuous thermal current of up to 1100 amperes.
The outstanding feature of the CT range is the unprecedented combination of electromagnetic and permanent-magnetic blowout in one device. In contrast with power contactors with only electromagnetic blowout, the electric arcs are ignited in strong permanent-magnetic blowout fields at the moment of shutdown.
The dwelling times of the electric arcs in the contact zones are thus kept to an absolute minimum. This leads to a significant reduction in shutdown combustion residue. This less wear on the contact surfaces allows for extended maintenance intervals.
The CT concept can be flexibly adjusted to the requirements of customers; e.g. the number of poles, auxiliary contact design or connection technology. The product family of the single and two-pole CT contactors covers a large number of different designs for a wide number of areas of application.
