KRAUS & NAIMER Short Form Catalogue

Discrepancy switch Mosaic panel board. Maintenance and Safety Switches consist of switch disconnectors equipped in high strength durable plastic enclosures which were designed with extra space for easy wiring.

With specific models for all current ratings they offer an ideal solution for a wide variety of applications. Safety switch interlocks with lid naomer prevent opening in ‘ON’ position are supplied with enclosures. Handle changeover switch Diagram Mounting.

As the miniature version of the series, the CG4 re-defined miniaturization in low-voltage switching. Until now the extra safety resulting from using ring type terminals had required extra effort and time to connect them.

Main switches are equipped with electro-gray or black handles.

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. Auxiliary contacts close after the main contacts close and open before main contacts open.

They are designed for switching of resistive or low-inductive loads. Fingerproof terminals, accessible either horizontally or vertically, captive plus-minus screws and integrated krauss guides designed for the use of motorized screwdrivers are some clear practical advantages of nsimer CA-Series. Guide Guide of handles Catalogues. Another advantage relating to installation is the integrated snap-on feature for DIN-rails on base mounted switches up to A.


Reduced arcing time Compact design Not polarity sensitive Up to V. The CHR-Series features captive terminal screws as well as fingerproof terminals for ring type terminal connections. Axial arrangement of the terminals allows mounting of CG-switches in very close proximity of each other. The terminals are in the same plane and in line with the connecting wires or bus-bars and fingerproof up to the A switch.

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.

It can be ordered separately as K3A D With rated operational currents from 16 amps to 64 amps and voltages from 80 to naimee a utilization category of DCB or DCA, a solution for most isolator applications within the solar photovoltaic market can be krus.

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. 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.

CH10, CH16 ring terminal: For low-voltage applications down to switching of electronic signals the CA4 and CA are offered. Extra safety without extra effort: Forced opening and closing main contacts are standard.


Each enclosure has either knock-outs for metric threads according to EN or metric niamer conduit entries on top and bottom. Approval Declarations of conformity Product certification. Voltmeter selector Diagram Mounting.

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

KG-switches are extremely compact while featuring unusually large isolation distances between open contacts for maximum safety. The arcing time has been reduced to some milliseconds using permanent magnets in the contact body. Disconnectors for Photovoltaic DC Applications: See Mounting Diagrams for details.

All enclosures are equipped with a ground terminal. Maintenance and Safety Switch enclosures are available with high UV-resistance or against an aggressive environment. Using this optional extra countering is not necessary for tightening the terminal screws.

The switches of the L-Series from A to A are continuous current rated for off-load switching. In this way the terminal screws can be reached oblique from the front Base mounting or the niamer Panel mounting. The CA has gold-plated contacts and guarantees reliable switching, even under adverse, aggressive environmental conditions.
