Cam switch 16A, Three-phase starter switch (0,Y,A), in OB2 enclosure. ŁK16R-4.831\OB2

Three-phase starter switch – reliable control of motors and devices

This three-phase cam switch ŁK16R-4.831\OB2 is a solid solution for manual switching on and off of electrical circuits, particularly useful for controlling motors, transformers and other devices with a power of up to 8 kW (at 400V). The construction in OB2 housing provides protection against external conditions and facilitates mounting.

Functionality and application

The cam switch allows for the implementation of various connection programs depending on the knob position (0, Y, Δ), making it a versatile element in electrical installations. This is particularly important in applications requiring a change in circuit configuration, e.g. when starting asynchronous motors. The device complies with EN 60 947-3:1992, which guarantees its safety and reliability.

• Application: manual switching on and off of current circuits, controlling electric motors, low-power transformers and other devices.
• Configuration: 0-Y-Δ switch enables flexible load control.
• Professional application: ideal for installers working on the construction and modernization of electrical installations in industry, construction and the energy sector.
• Home/utility application: suitable for applications where manual control of higher-power devices is required, e.g. pumps, actuators.

Construction and characteristic features

The switch is made of durable plastic, which ensures its durability and resistance to mechanical damage. The IP65 protection class guarantees protection against dust and water jets, allowing installation in various environmental conditions. Screw terminals provide a secure connection of wires. The complete construction in the housing facilitates mounting and provides additional protection of internal elements.
