Cam switch 40A, Disconnector 0-1 (4-pole), long black knob ŁK40-2.8210\P09

Cam switch – reliable switching in electrical installations

This four-pole cam switch with a rated current of 40A is a versatile device designed for switching electrical circuits on and off. The 0-1 disconnector design allows for safe isolation of the load, which is particularly important during maintenance or repair. Equipped with a long, black knob, it provides convenient operation even in difficult conditions.

Construction and application

A cam switch is an element used to manually switch electrical circuits. It finds wide application in industrial installations, construction, and workshops, where reliability and the ability to quickly disconnect power are required. Thanks to the IP65 protection class, it is resistant to dust and water ingress, allowing it to be used in demanding environments. Made of durable plastic, it provides durability and resistance to mechanical damage. The possibility of indirect mounting increases installation flexibility.

Key features and benefits

• High mechanical resistance: The housing made of plastic guarantees durability and corrosion resistance.
• Safety of use: The 0-1 disconnector allows for complete isolation of the circuit, minimizing the risk of electric shock during maintenance work.
• Versatility: Indirect mounting option makes installation easier in various configurations.
• Resistance to external conditions: IP65 protection class protects against dust and water, ensuring reliable operation even in difficult environmental conditions.
• High switching power: The rated operating power for AC-3 is 20 kW at 400V, allowing it to handle demanding loads.
• Designed for frequent switching: Durable construction ensures long life even with intensive use.
• Easy operation: The long black knob provides a firm grip and convenient circuit switching.
• Safety confirmed by standards: Compliance with standards ensures a high level of safety.

Technical parameters in practice

The rated continuous current of 40A and the high switching power (20kW for AC-3) make this switch perfect for applications requiring high power consumption. Screw connection of the main contacts guarantees a secure and durable connection of the wires. The lack of auxiliary contacts (normally open and normally closed) simplifies the construction and reduces installation costs, while fulfilling the basic functions of switching circuits. The housing material - plastic - provides good electrical insulation and resistance to mechanical damage and atmospheric factors (within the limits permissible by IP65 class).
