CT power contactors – Revolution in handling DC and AC electric arcs

Single and double pole NO contactors for AC and DC (bidirectional). Rated insulation voltage up to 4,800 V; conventional thermal current up to 1,100 A.

Description

Detailed description

“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.”
