Cam switch disconnector 25A, 1-0-2 switch (1-pole), in OB2 enclosure with lockable front ŁK25R-1.834\OB2Z

Universal cam switch – reliable switching in your installation

This cam switch, with a rated current of 25A, is a solid solution for frequent circuit switching. The 1-0-2 (1-pole) design allows for flexible device control, and the OB2 housing provides protection against external factors. This device is suitable for both industrial applications and building installations where reliability and safety are required.

Construction and application

A cam switch is an element used to manually switch electrical circuits. This model, with a closed front, is characterized by a high degree of protection (IP65), which makes it resistant to dust and moisture. The use of plastic for the housing provides lightness and good insulation. The switch with a knob enables convenient and precise change of the circuit state. This is particularly useful in situations where manual control over the power supply is needed, e.g. when servicing machines or in emergency systems.

Key features and benefits

• Mechanical durability: Designed for intensive use – withstands up to 3 million switching cycles. This guarantees a long service life even with frequent switching.
• Safety: IP65 protection rating protects against contact with moisture and dust, minimizing the risk of short circuits and damage.
• Versatility: Possibility of mounting in various configurations thanks to a wide range of available models (different number of poles).
• Resistance to external conditions: Wide operating temperature range (-40°C to +70°C) allows it to be used in harsh environmental conditions.
• Adapted to different wire cross-sections: Supports wires with a cross-section of 2.5 mm² to 6 mm², which facilitates integration with the existing installation.
• High switching power: Rated operating power for AC-3 is as high as 13 kW at 400V – sufficient for most industrial and construction applications.
• Solid construction: Made of high-quality materials ensuring reliable operation for a long time.
• Continuous rated current: 25A ensures stable operation under load.

Operating parameters

The device is characterized by high resistance to vibrations and mechanical shocks, which is particularly important in industrial applications. The rated conditional short-circuit current is 13 kA, which provides effective protection against the effects of short circuits. The rated insulation voltage is 690V, and the impulse withstand voltage – 6kV, which guarantees safety of use in various electrical installations. The tightening torque of the terminals is 1.2 Nm – ensures a secure connection of the wires without the risk of damage to the terminals.
