4G Series Cam Switches – a reliable solution for demanding installations

Apator 4G series cam switches are devices designed for safe and efficient switching of electrical circuits. Developed using modern technologies and high-quality materials, these switches find application in various industrial, mining, marine installations, as well as in transformer stations and switchgear. This particular model, 4G16-10-U, is a three-pole switch with a “0” position, designed for flush mounting.

Functionality and application

This cam switch is a versatile device for manual circuit switching. It has a clear “0” position, which provides additional safety during maintenance and repairs. A rated continuous current of 16A and the ability to operate at up to 690V~ make it an ideal choice for medium-power circuits. It can be used in control cabinets, switchboards and other devices requiring reliable circuit switching.

Key features and benefits

• Durable construction: The use of high-quality insulating materials and contacts guarantees long life and reliability of the device.
• Versatility: Can be used in various types of installations – industrial, mining, marine.
• Safety: Clear “0” position increases safety during maintenance and repair work.
• High rated power: Rated power for AC-3 at 8 kW allows operation of devices with significant power consumption.
• Easy mounting: Designed for indirect mounting, which simplifies integration with existing systems.
• Solid connections: Screw connections used provide secure and durable connection of wires.
• Universality: Model U (without housing) provides flexibility in choosing the appropriate housing adapted to the specifics of the installation.

Technical parameters in practice

This switch has been designed with performance and reliability in mind. A rated continuous current of 16A means it can safely handle devices with a constant power consumption up to this value. In turn, the rated power for AC-3 of 8 kW indicates its ability to switch inductive loads, such as electric motors. The IP40 degree of protection provides protection against access to hazardous live parts and against the ingress of solid objects larger than 1 mm – which is important in industrial environments. Indirect mounting allows for flexible adaptation of the switch to different installation configurations.
