Changeover switch 16A, direction of rotation change switch L-0-P, in OB3 housing. ŁK16R-3.8368\OB3

Rotary cam switches – reliable control of electrical circuits

This 16A rotary cam switch, designed for changing the direction of rotation (L-0-P), is a solid and functional solution for controlling motors and other electrical devices. Housed in a durable OB3 enclosure, it provides protection against external factors and guarantees long-lasting, trouble-free operation. It is an ideal element for both industrial applications and installations requiring frequent switching of loads.

Construction and application

A rotary cam switch is a mechanical device used to switch electrical circuits on and off. The ŁK16R-3.8368\OB3 model is distinguished by its ability to change the direction of motor rotation – the L-0-P function allows for smooth switching between left-hand operation, off (position 0) and right-hand operation. The design with double cams allows for the creation of connection programs tailored to specific application needs. Thanks to this, it finds application in various installations where precise control of electrical devices is required.

Key features and benefits

• Durable construction: The housing made of plastic provides resistance to mechanical damage and atmospheric factors. The IP65 protection class guarantees protection against dust and water jets, allowing operation in harsh environmental conditions.
• Universal application: The direction of rotation change function (L-0-P) makes the switch ideal for controlling electric motors, pumps and other devices requiring a change in the direction of work.
• Safety of use: Rated continuous current of 16A and high short-circuit resistance (up to 13 kA) ensure safe and reliable operation of the electrical installation.
• Easy installation: Screw connection of the main contacts facilitates connection of wires, and the possibility of mounting on a rail allows for quick integration with the existing electrical infrastructure.
• Wide temperature range: The device retains its properties in the temperature range from -40°C to +70°C, allowing it to be used in various climatic conditions.
• Compliance with standards: Meets the requirements of PN-EN 60947-3 and IEC 60947-3, which confirms its high quality and safety of use.
• Durability: Mechanical durability of 3 million switching cycles guarantees long-term and trouble-free operation of the device.

Technical parameters in practice

The rated power for AC-3 at 400V is 8 kW – this means that the switch can safely handle devices with a power of up to 8 kW at standard mains voltage. High resistance to vibrations and shocks (compliant with IEC standards) ensures stable operation even in environments with high vibration intensity. The cross-section of connection wires 1.5…4 mm² allows connection of wires of different thicknesses, adapting to individual installation needs.
