Disconnect switch 63A, 0-1 (3-pole), front panel mounting grey, black knob ŁK63-2.8211\S03

Cam switch – reliable circuit switching

This three-pole cam switch with a rated current of 63A is a solid solution for switching electrical circuits. Designed for both rail mounting and built-in installation, it finds application in low-voltage electrical installations where reliability and safety are required. Model ŁK63-2.8211\S03 is distinguished by its high quality of workmanship and configuration options thanks to the various available covers.

Construction and application

The cam switch is used to switch electrical circuits on and off, as well as to change the direction of rotation of motors. The construction with position 0 (off) provides additional safety of use. Made of durable plastic, it is resistant to mechanical damage and environmental influences. Rail mounting allows for easy integration with existing electrical infrastructure. The IP65 cover guarantees protection against dust and moisture, making it an ideal solution for use in harsh industrial conditions or outdoors.

Key features and benefits

• High mechanical resistance: The housing made of plastic ensures durability and resistance to damage.
• Safety of use: It has position 0 (off), which minimizes the risk of accidental circuit activation.
• Wide range of applications: Suitable for installation in residential, commercial buildings and in industry.
• Easy installation: Rail mounting makes installation and integration with existing systems easier.
• Environmental protection: IP65 protection class guarantees resistance to dust and moisture.
• High switching power: The rated operating power for AC-3 is as high as 20 kW at 400 V, allowing it to handle demanding loads.
• Suitable for continuous operation: The rated continuous current Iu is 63 A, which ensures stable operation even under heavy load.
• Configuration flexibility: Availability of different types of covers allows you to adapt the switch to individual user needs (e.g. cover lockable with a padlock).

Technical parameters in practice

The rated continuous current of 63A means that the switch can safely operate with a load of this value for a long time without overheating. The rated switching power of 20 kW at 400V demonstrates its ability to handle devices with significant power, such as electric motors or industrial heaters. The rated short-circuit current Icm at 2.2 kA indicates its resistance to short-term overvoltages associated with short circuits in the electrical network. The mechanical durability of 3 million switching cycles guarantees a long service life even with intensive use. Screw connection of the main contacts ensures a secure and reliable connection of wires with a cross-section from 4 to 10 mm².
