Kraus & Naimer Rotary Knob Actuator, 2 Position, 10A, 690V, IP40, Panel Mount CG4.A291/GBA121.EF

Kraus & Naimer CG4.A291/GBA121.EF is a high-quality rotary knob actuator designed to deliver reliable manual switching for a wide range of electrical automation and industrial applications. Featuring a comprehensive panel-mount design, this actuator provides two discrete positions that allow users to precisely control circuits, offering straightforward operation and versatile switching for control panels, machinery interfaces, and process automation systems.

Built to withstand demanding environments, the actuator is rated for a contact current of 10A and a maximum contact voltage of 690V, enabling safe operation under industrial loads. The IP40 ingress protection guards against solid particles larger than 1mm, making it suitable for indoor installations and protected locations. Its robust screw terminal connections simplify installation and maintenance, ensuring firm and consistent electrical contact.

The actuator utilizes a rotary knob mechanism for easy and ergonomic operation, and the square 30mm escutcheon plate ensures compatibility with standard panel cutouts. With a mechanical life of 1,000,000 operations, this device offers extended service in environments requiring frequent actuation, such as manufacturing lines, distribution boards, and control cabinets. The product’s dimensions - 30mm length, 30mm width, and 38.5mm depth - make it unobtrusive yet easily accessible in panel layouts.

Its wide operating temperature range from -25°C to 55°C allows reliable use in varied climate conditions. Certification to IEC 60947-3 ensures compliance with international safety and performance standards, making it suitable for regulated applications. The rotary knob actuator's two-pole setup facilitates switching independent circuits, further increasing operational versatility.

Typical use cases include industrial and commercial electrical panels, automation controller interfaces, machinery controls, and instrumentation panels where reliable manual circuit switching is crucial. Its European origin (Austria) attests to quality manufacturing and adherence to engineering standards.
