Cam switch disconnector 25A, 0-1 switch (4-pole), in OB4 enclosure with lockable front ŁK25R-2.8210\OB4Z

Universal cam switch for various applications

This four-pole cam switch with a rated current of 25A is a reliable solution for switching electrical circuits. Designed for both professional and domestic applications, it provides safe and convenient operation. Equipped with a "0" position, it allows for complete disconnection of the circuit, increasing safety during maintenance or repairs. The OB4 housing with a lockable front guarantees protection against dust and moisture (IP65), making it an ideal choice for industrial environments and damp rooms.

Design and operating parameters

The switch is characterized by a solid plastic construction, ensuring durability and resistance to mechanical damage. Installation is done using screw connections, which simplifies installation and ensures a secure connection of the wires. Designed to operate with a rated insulation voltage of 690V and an impulse voltage of 6kV, it can withstand even harsh operating conditions. The rated operating power at AC-3 (400V) is 13 kW, making it suitable for medium-power loads. It is worth noting the high short-circuit current that the switch can withstand – as much as 1 kA – which provides additional safety for the installation.

Functionality and application

A cam switch is a device used for manual switching of electrical circuits. Its versatility makes it applicable in many areas:

• Industry: controlling motors, lighting of machines and production equipment.
• Construction: switching lighting, heating or ventilation circuits in residential and commercial buildings.
• Workshops and garages: controlling lighting, power tools and other devices.
• Home installations: as an element of electrical switchboards, allowing convenient switching of various energy consumers.

Thanks to its design and technical parameters, this switch is a reliable tool for installers and a convenient solution for end-users looking for a safe and functional device for switching electrical circuits.
