Cam switch disconnector 25A, 0-1 (3-pole) switch, in OB4 enclosure with lockable front ŁK25-2.8211\OB4Z

Robust construction for demanding applications

The 25A cam switch is a reliable device designed for frequent switching of electrical circuits. This model, equipped with a 0-1 switch and an OB4 enclosure with a lockable front, ensures safe and convenient operation. It is an ideal solution for both installers and end-users who need a solid and durable switch.

Functionality and safety in one

This three-pole cam switch (25A) allows for manual switching of circuits on and off. The OB4 enclosure provides a high degree of protection IP65, which guarantees resistance to dust and moisture – particularly important in harsh industrial or outdoor conditions. The lockable front provides additional protection against accidental contact with conductive elements.

• Designed for frequent switching: The switch design allows for multiple on/off cycles without risk of damage.
• High mechanical resistance: Durable materials ensure long-term reliability even in demanding working conditions.
• Safety of use: IP65 enclosure protects against moisture and dust, and the lockable front minimizes the risk of electric shock.
• Versatility of application: Suitable for a variety of applications, from industrial installations to residential construction.
• Wire cross-section 2.5...6 mm²: Allows connection of wires of different thicknesses, adapting to the needs of the installation.
