It can be ordered separately as K3A D See Mounting Diagrams for details. 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. Using this optional extra countering is not necessary for tightening the terminal screws.

Each enclosure has either knock-outs for metric threads according to EN or metric treated conduit entries on top and bottom. CH10, CH16 ring terminal: The terminal screw had to be fully removed to position the ring type terminal before the screw could be re-inserted in a fairly cumbersome fashion.

Extra safety without extra effort: The time required for loosening the terminal screws, stripping, preparing of the conductors and tightening of the terminal screws again can be saved.

Up on request the switch disconnectors are available with door clutch systems and padlock devices. The CA has gold-plated contacts and guarantees reliable switching, even under adverse, aggressive environmental conditions.

Until now the extra krus resulting from using ring type terminals had required extra effort and time to connect them. With specific models for all current ratings they offer an ideal solution for kaus wide variety of applications. Safety switch interlocks with lid to prevent opening in ‘ON’ position are supplied with enclosures.


The Naaimer with fingerproof terminals from 10 A to 32 A is ideally suited for many standard applications where industrial controls, instrumentation and electric motors are involved. Disconnectors for Photovoltaic DC Applications: The terminals are in the same plane and in line with the connecting wires or bus-bars and fingerproof up to the A switch.

Kraus & Naimer – Control Switches

Large terminals with captive screws and fingerproofing up to A are valuable practical advantages as is the integrated screwdriver guide for the use of motorized screwdrivers. CH10, CH16 Ring terminal: 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.

Main switches with emergency function are supplied with red handle and contrasting yellow face plate. The CG-Series saves space: Guide Guide of handles Catalogues. Kraue switch Mosaic panel board. The switches of naimef L-Series from A to A are continuous current rated for off-load switching. The CHR-Series for ring type terminals. The arcing time has been reduced to some milliseconds using permanent magnets in the contact body.

Maintenance and Safety Switch enclosures are available with high UV-resistance or against an aggressive environment. Cb10 arrangement of the terminals allows mounting of CG-switches in very close proximity of each other. Another advantage relating to installation is the integrated snap-on feature for DIN-rails on base mounted switches up to A.

To complement this series a complete range of AC switch disconnectors is also available in totally insulated enclosures, naime enables the contractor to obtain his switch disconnector requirements for the entire installation from one source.

As the miniature version of the series, the CG4 re-defined miniaturization in low-voltage switching. Auxiliary contacts close after the main contacts close and open before main contacts open.

Other values on request. Approval Declarations of conformity Product certification.

The CHR-Series features captive terminal screws as well as fingerproof terminals for ring type terminal connections. With rated operational currents from 16 amps to 64 amps and voltages from 80 to using a utilization category of DCB or DCA, a solution for most isolator applications within the solar photovoltaic market can be found. For low-voltage applications down to switching of electronic signals the CA4 and CA are offered.

Maintenance and Safety Switches consist of switch disconnectors equipped in high strength durable plastic enclosures which were iraus with extra space for easy wiring. Fingerproof terminals, accessible either horizontally or vertically, captive plus-minus screws and integrated screwdriver guides designed for the use of motorized screwdrivers are some clear practical advantages of the CA-Series. Forced opening and closing main contacts are standard.

All enclosures are equipped with a ground terminal. They are designed for switching of resistive or low-inductive loads. Voltmeter selector Diagram Mounting.

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. In this way the terminal screws can be reached oblique from the front Base mounting or the rear Panel mounting.

Main switches are equipped with electro-gray or black handles. Handle changeover switch Diagram Mounting. Reduced arcing time Compact design Not polarity sensitive Up to V.

KG-switches are extremely compact while featuring unusually large isolation distances between open contacts for maximum safety.
