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.

Other values on request. As the miniature version of the series, the CG4 re-defined miniaturization in low-voltage switching. Each enclosure has either knock-outs for metric threads according to EN or metric treated conduit entries on top and bottom.

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.

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. See Mounting Diagrams for details. Axial arrangement of the terminals allows mounting of CG-switches in very close proximity krzus each other. Using this optional extra countering is not dh10 for tightening the terminal screws.

Safety switch naimdr with lid to prevent opening in ‘ON’ position are supplied with enclosures. Auxiliary contacts close after the main contacts close and open before main contacts open. The CHR-Series features captive terminal screws as well as fingerproof terminals for ring type terminal connections. It can be ordered separately as K3A D CH10, CH16 ring terminal: They are designed for switching of resistive or low-inductive loads.


All enclosures are equipped with a ground terminal. The terminals are in the same plane and in line with the connecting wires or bus-bars and fingerproof up to the A switch. Main switches are equipped with electro-gray or black handles. The CA-Series with fingerproof terminals from 10 A to 32 A naimdr ideally suited for many standard applications where cj10 controls, instrumentation and electric motors are involved.

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.

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.

Discrepancy switch Mosaic panel board. CH10, CH16 Ring terminal: Up on request the switch disconnectors are available with door clutch systems and padlock devices. The CHR-Series for ring type terminals. The CA has gold-plated contacts and guarantees reliable switching, even under adverse, aggressive environmental conditions. In this way the terminal screws can be reached oblique from the front Base mounting or the rear Panel 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.

Disconnectors for Photovoltaic DC Applications: Forced opening and closing main contacts are standard. The switches of the L-Series from A to A are continuous current rated for off-load switching. The time required for loosening the terminal screws, stripping, preparing of the conductors and tightening namer the terminal screws again can be saved.

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

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

Extra safety without extra effort: For low-voltage applications down to switching of electronic signals the CA4 and CA are offered.

Main switches with emergency function are supplied with red handle and contrasting yellow face plate. The arcing time has been reduced to some milliseconds using permanent magnets in the contact body. The CG-Series saves space: Until now the extra safety resulting from using ring type terminals had required extra effort and time to connect them.

Approval Declarations of conformity Product certification. Reduced arcing time Compact design Not polarity sensitive Up to V. 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.

Guide Guide of handles Catalogues. Maintenance and Safety Switches consist of switch disconnectors equipped in high strength durable plastic enclosures which were designed with extra space for easy wiring. Maintenance and Safety Switch enclosures are available with high UV-resistance or against an aggressive environment. With specific models for all current ratings they offer an ideal solution for a wide variety of applications. Handle changeover switch Diagram Mounting.
