Cam switch 25A, Disconnector 0-1 (3-pole), in OB4 enclosure. ŁK25-2.8211\OB4

Robust cam switch for demanding applications

This three-pole cam switch with a rated current of 25A is a reliable solution for frequent circuit switching. It is used in controlling motors, machines and electrical equipment where high mechanical and electrical resistance is required. Model ŁK25-2.8211\OB4, housed in a durable OB4 enclosure, guarantees safety and durability even in harsh industrial conditions.

Functionality and parameters

The switch is characterized by high resistance to shocks and vibrations, making it an ideal choice for applications in demanding environments. Suitable for operation in a wide temperature range (from -40°C to +70°C) and a high degree of protection IP65 with respect to the panel ensure reliable operation in various conditions. The rated conditional short-circuit current of 13 kA provides effective protection of the installation against the effects of short circuits.

This switch ensures safe operation with loads thanks to the continuous rated current of 25A. It can be used in installations with different voltages, as the rated insulation voltage is 690V. The rated switching power (AC-3) is 7 kW at 230V, 13 kW at 400V and 10 kW at 690V, respectively, allowing control of motors of different power. Long service life and reliability of the device are guaranteed by the mechanical durability of 3 million switching cycles. The IP65 degree of protection protects against water jets and dust, making it an ideal solution for industrial applications. The cross-section of connection cables from 2.5 to 6 mm² facilitates the connection of cables of different thicknesses.

Construction and application

The cam switch with OB4 enclosure is a combination of solid construction and functionality. The enclosure protects against mechanical damage and external factors, and the cam mechanism ensures smooth and reliable circuit switching. Thanks to the possibility of panel mounting, the device is easy to operate and integrate with existing control systems. A wide range of available disconnectors (0-1, 1-0-2) allows adaptation to specific application needs. Additionally, direction of rotation switches and other control elements are available, which increases the versatility of the device.
