Cam switch disconnector 63A, 0-1 switch (3-pole), front mounting on DIN rail, lockable, yellow/red ŁK63-2.8211\S08

Cam switch – reliable switching in your installation

This three-pole cam switch with a rated current of 63A is a solid solution for switching electrical circuits. Designed for both indoor and industrial environments, it provides safe and convenient operation. Model ŁK63-2.8211\S08 is distinguished by its versatility thanks to the possibility of busbar mounting, and its lockable design increases the level of security.

Functionality and application

The cam switch is used to switch electrical circuits on and off, offering a "0" position for complete isolation. It will be useful in installations requiring frequent switching of the load, e.g. when powering machines and equipment. Thanks to the high rated current (63A) and switching power up to 20 kW (at 400V), it is suitable for use in industry, workshops and commercial buildings. The possibility of busbar mounting facilitates integration with the existing electrical infrastructure.

Key features and benefits

• High mechanical resistance: Mechanical durability at the level of 3 million switching cycles guarantees long-lasting and trouble-free operation.
• Safety of use: The IP65 protection class protects against dust and water, ensuring safe operation even in harsh environmental conditions. The lockable design provides additional protection against unauthorized access.
• Wide range of voltages: The ability to operate at an insulation voltage of up to 690V and impulse voltage of up to 6kV ensures compatibility with various electrical systems.
• Universal mounting: Designed for busbar mounting, which facilitates installation and integration with existing infrastructure.
• Adapted to work in difficult conditions: A wide range of operating temperatures (-40°C to +70°C) allows the switch to be used in various industrial environments.
• Solid construction: Made of high-quality plastic, which ensures durability and resistance to mechanical damage.
• High switching power: Rated switching power AC-3 up to 20 kW (400 V) allows operation of demanding loads.
• Short-circuit current: Short-circuit current resistance of 1.2kA provides additional safety for the installation.

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 the risk of overheating or damage. The rated switching power Pe in category AC-3 (up to 20 kW at 400V) indicates the switch's ability to switch on and off motors and other inductive devices with a specific power. The IP65 protection class guarantees protection against dust and water jet, which is particularly important in humid or dusty working environments. The lockable design provides additional protection against unauthorized access and manipulation, which increases the safety of the entire electrical system.
