Cam switch 63A, Dahlander two-speed switch, panel mounting front gray knob black ŁK63-4.8390\P03

Universal cam switch for demanding applications

This 63A cam switch, also known as a Dahlander switch, is a robust solution for controlling electrical circuits. Designed for both panel mounting and enclosure installation, it offers reliable operation and high resistance to environmental conditions. The plastic construction provides good insulation and durability. A black knob facilitates operation and allows for precise circuit switching.

Functionality and application

This switch is ideal for applications requiring frequent load switching, such as controlling motors, heaters or other high-power devices. Its two-pole design allows for flexible adaptation to installation needs. The possibility of indirect mounting increases the range of applications, and the high degree of protection IP65 guarantees safety in harsh industrial conditions. The Dahlander switch allows you to change the direction of motor rotation or switch between different speeds.

Key features and benefits

• High resistance: IP65 protection rating protects against dust and moisture, making it ideal for use in harsh industrial environments.
• High rated power: Rated power AC-3 at 20 kW (at 400 V) enables control of even large loads.
• Suitable for frequent switching: Mechanical durability of 3 million switching cycles ensures long-lasting and reliable operation.
• Universal mounting: Possibility of indirect mounting and in enclosures increases installation flexibility.
• Safety: Rated insulation voltage Ui 690 V and impulse withstand voltage Uimp 6 kV provide a high level of safety.
• Solid construction: Made of high-quality plastic, resistant to mechanical damage and external factors.
• Continuous rated current: 63A ensures stable operation even under heavy load.
• Application in various environments: Wide temperature range (-40°C to +70°C) enables use in various environmental conditions.

Technical parameters in practice

The rated continuous current Iu at 63A means that the switch can safely operate with a load of that intensity for a long time without overheating. The rated switching power Pe in category AC-3 (20 kW at 400 V) indicates its ability to effectively switch inductive loads, such as electric motors. High resistance to vibration and shock (compliant with IEC 60068-2-6 and IEC 60068-2-27 standards) guarantees reliable operation even in demanding industrial conditions. The cross-section of connection cables from 4 to 10 mm² ensures compatibility with various types of electrical installations.
