Cam switch disconnector 40A, Isolator 0-1 (4-pole), in OB4 housing with lockable front ŁK40-2.8210\OB4Z

Cam switch – reliable switching in your installation

This four-pole cam switch with a rated current of 40A is a solid solution for frequent switching of electrical circuits. Equipped with a 0 position, it provides additional safety during maintenance and repairs. The construction in OB4 housing with a lockable front guarantees high resistance to external conditions and mechanical damage, making it an ideal choice for both industrial applications and public buildings.

Construction and application

A cam switch is a device used to manually switch electrical circuits. This model, thanks to its design, is particularly useful where reliability and the ability to switch frequently are required. Designed for mounting on a rail or directly on the device, it offers flexibility in installation. Made of durable plastic, it provides good insulation and corrosion resistance. The cam mechanism allows for smooth and precise switching between circuits.

Key features and benefits

• High resistance to external conditions: IP65 protection class guarantees protection against dust and water jets, allowing the switch to be used in harsh environmental conditions.
• Safety of use: The presence of the 0 position allows for complete disconnection of the circuit during maintenance or repair work, minimizing the risk of electric shock.
• Durable construction: The housing made of plastic and the solid cam mechanism ensure a long service life even with intensive use (mechanical durability is as many as 3 million switching cycles).
• High switching power: The rated operating power for AC-3 is 20 kW at 400 V, allowing connection of even demanding receivers.
• Easy installation: Screw connection of the main contacts facilitates the connection of wires with a cross-section of 4-10 mm².
• Versatility: Can be used in various electrical installations – from industrial to commercial.
• Compliance with standards: The device meets appropriate safety standards, confirming its high quality and reliability.

Additional information: the switch is adapted to work in a wide range of ambient temperatures (-40°C to +70°C) and is characterized by high resistance to vibrations and shocks. Thanks to this, it can be used without fear in demanding industrial applications.
