DC Contactor Kiepe GN

The Kiepe GN series DC contactors are electromagnetic switches in accordance with VDE 0660, Part 1/3.68. They have proven themselves successful for decades in their current design.

The requirements for trackless electric battery vehicles in accordance with DIN 43 553/1.73 have been largely taken into consideration. The insulation requirements of the contactor, the clearance and creepage distance are met in accordance with DIN EN 50 124-1:2001.

The Kiepe GN series electromagnetic DC contactors are made in a 1-pole and/or 2-pole design. They are used for the switching of DC motors and in DC onboard power systems - e.g. as a battery contactor.

The contactors are switched on with DC solenoids and the resetting is carried out by spring tension. The solenoids are available for 3 operation ranges.
Range 1 (+10/-30 %) is especially suitable for battery-powered systems, range 2 (+10/-15 %) for industrial DC power systems and range 3 (+20/-30 %) for train applications. For protection from transient voltage spikes during the switching off of the solenoids, these can be equipped with a varistor as voltage surge protection. The drive magnets are equipped with a 6.3 mm fast-on connector.

As an auxiliary switch, up to 2 ausiliary switch blocks can be attached. Every auxiliary switch block das 1 normally open contact and 1 normally closed contact. The auxiliary switches are equipped with a 6.3 mm fast-on connector.

The main contact - with double interruption - is designed for rated voltages up to DC 600 V. A permanent magnetic blower device is integrated for extinguishing the electric arc when being switched off. The correct polarity should therefore be acertained during connection. The switching capacity was checked corresponding to VDE 0660/Part 102 with the switching categories DC 1, DC 2/3 and DC 4/5.

If the contacts are parallelly switched with the2-pole contactor, the rated thermal current is reduced to the values given in the technical data for parallel switching. The main contacts are equipped with a M10 screw terminal.

The contactor is constructed on a steel base plate, which at the same time serves as the mounting. During the planning of the installation, the required minimum distances and the possible assembly positions are to be observed.

The contactors are meant for installation in rooms where no difficult operating conditions occur due to effects of dust, moisture or atmospheric influences.
