Maintenance and Safety Switches consist of switch disconnectors equipped in high strength durable plastic enclosures which were designed with extra space for easy wiring. Each enclosure has either knock-outs for metric threads according to EN or metric treated conduit entries on top and bottom.

Safety switch interlocks with lid to prevent opening in ‘ON’ position are supplied naimet enclosures. Main switches are equipped with electro-gray or black handles. Main switches with emergency function are mraus with red handle and contrasting yellow face plate. Maintenance and Safety Switch enclosures are available with high UV-resistance or against an aggressive environment.

All enclosures are cg10 with a ground terminal. Auxiliary contacts close after the main contacts close and open before main contacts open. Disconnectors for Photovoltaic DC Applications: 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.

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


The arcing naimerr has been reduced to some milliseconds using permanent magnets in the contact body. Up on request the switch disconnectors are available with door clutch systems and padlock devices.

Other values on request. With specific models for all current ratings they offer an ideal solution for a wide variety of applications.

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. For low-voltage applications down to switching of electronic signals the CA4 and CA are offered. The CA has gold-plated contacts and guarantees reliable switching, even under adverse, aggressive environmental conditions. 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.

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

Nimer switches of the L-Series from A to A are continuous current rated for off-load switching. They are designed for switching of resistive or low-inductive loads. See Mounting Diagrams for details.

In this way the terminal screws can be reached oblique from the front Base mounting or the rear Panel mounting. The CG-Series saves space: Axial arrangement of the terminals allows mounting of CG-switches in very close proximity of each other.

As the miniature version c1h0 the series, the CG4 re-defined miniaturization in low-voltage switching. Extra safety without extra effort: The CHR-Series for ring type terminals. Until now the extra safety resulting from using ring type terminals had required extra effort and time to connect them. 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 CHR-Series features captive terminal screws as well as fingerproof terminals for ring naijer terminal connections.


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 A 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 A 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 A. 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.

Using this optional extra countering is not necessary for tightening the terminal screws. It can be ordered separately as K3A D Approval Declarations of conformity Product certification.
