KG-switches are extremely compact while featuring unusually large isolation distances between open contacts for maximum safety. Forced opening and closing main contacts are standard.

The terminals are in the same plane and in line with the connecting wires or bus-bars and fingerproof up to the 160A switch.
On-Off switches are available with three to eight poles, double-throw switches with three or four poles and a special version for applications in motor control centers is available. This variability provided by the modular design system, power ratings for every application, and two different design variants permit optimization of KG-switches for a large variety of requirements.

Large terminals with captive screws and fingerproofing up to 160A are valuable practical advantages as is the integrated screwdriver guide for the use of motorized screwdrivers. Another advantage relating to installation is the integrated snap-on feature for DIN-rails on base mounted switches up to 160A.

The many optional extras for the KG-series include shaft extensions, door clutches, neutral and ground terminals, up to eight auxiliary contacts, terminal covers and various locking devices.

Kraus & Naimer has designed a wiring aid for switch types KG126, KG127, KG161 and KG162. Using this optional extra countering is not necessary for tightening the terminal screws. It can be ordered separately as K3A D720 09.
