Reduced arcing time Compact design Not polarity sensitive Up to V.

Main switches with emergency function are supplied with red handle and contrasting yellow face plate. With specific models for all current ratings they offer an ideal solution for a wide variety of applications. In krauw way the terminal screws can be reached oblique from the front Base mounting or the rear Panel mounting.

Another advantage relating to installation is the integrated snap-on feature for DIN-rails on base mounted switches up to A.

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

Handle changeover switch Diagram Mounting. 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. For low-voltage applications down to switching of electronic signals the CA4 and CA are offered. Axial arrangement of the terminals allows mounting of CG-switches in very close proximity of each other.

CH10, CH16 ring terminal: Forced opening and closing main contacts are standard. Disconnectors for Photovoltaic DC Applications: Maintenance and Safety Switch enclosures are available with high UV-resistance or against an aggressive environment.


The arcing time has been reduced to some milliseconds using permanent magnets in the contact body.

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

The CA-Series 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. The CG-Series saves space: Discrepancy switch Mosaic panel board. The naimeer of the L-Series from A to A are continuous current rated for off-load switching. Using this optional extra countering is not necessary for tightening the terminal screws.

CH10, CH16 Ring terminal: The CHR-Series features captive terminal screws as well as fingerproof terminals for ring type terminal connections. All enclosures are equipped with a ground terminal. 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.

Each enclosure naime either knock-outs for metric threads according to EN or naimerr treated conduit entries on top and bottom. Voltmeter selector Diagram Mounting. They are designed for switching of resistive or low-inductive loads.

Up on request the switch disconnectors are available with door clutch systems and padlock devices. KG-switches are extremely compact while featuring unusually large isolation distances between open contacts for maximum safety.

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


Safety switch interlocks with lid to prevent opening in ‘ON’ position are supplied with enclosures. Approval Declarations of conformity Product certification. 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. Extra safety without extra effort: As the miniature version of the series, the CG4 re-defined miniaturization in low-voltage switching.

The time required for loosening the terminal screws, stripping, preparing of the conductors and tightening of the terminal screws again can be saved.

Until now the extra safety resulting from using ring type terminals had required extra effort and time to connect them. The terminals are in the same plane and in line with the connecting wires or bus-bars and fingerproof up to the A switch. Other values on request.

See Mounting Diagrams for naimmer. The CHR-Series for ring type terminals. 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.

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.
