Cam switch disconnector 40A, 0-1 switch (4-pole), in OB4 enclosure. ŁK40-2.8210\OB4

Universal cam switch for various applications

This four-pole cam switch with a rated current of 40A is a reliable solution for switching electrical circuits. Designed for both industrial and building installations, it offers high functionality and safety. Equipped with a "0" position, it allows for complete disconnection of the circuit, which is crucial during maintenance or repair. The OB4 housing provides protection against external factors and increases the durability of the device.

Construction and characteristic features

The switch is made of durable plastic, which ensures lightness and corrosion resistance. The IP65 protection class guarantees tightness against dust and water jets, allowing installation in harsh environmental conditions. The connection of the main contacts is made using screw connections, which ensures a secure and stable connection of wires with a cross-section from 4 to 10 mm². The switch has a knob that facilitates operation and precise positioning.

Application and benefits

This model combines the functionality of a disconnector (0-1) with the ability to switch circuits. Thanks to this, it finds application in:

• Industrial machines and equipment: as a control element for motors, heaters or other energy consumers.
• Building installations: for switching lighting, socket or heating circuits.
• Control panels: as a component of more complex automation systems.
• Service and maintenance: safe disconnection of circuits during repair work.

Rated values such as rated operating power for AC-3 (20 kW at 400V) and rated short-time withstand current (0.85 kA) demonstrate its high performance and reliability in demanding applications. Mechanical durability of 3 million switching cycles guarantees long device life even with intensive use. Vibration and shock resistance confirms its solid construction adapted to work in difficult industrial conditions.
