Cam switch 63A, three-phase starter switch (0,Y,A), panel mounting, grey front, black knob ŁK63-4.831\P03

Starter Switch – Reliable Control of Motors and Devices

This three-phase cam switch with a current of 63A is a solid solution for manual switching on and off of circuits, especially electric motors, transformers and other equipment requiring reliable disconnection from the power supply. The design allows switching between different circuit configurations (0-Y-∆), making it a versatile element in electrical installations.

Functionality and Application

The ŁK63 switch is designed for professional installations where safety and durability are important. It will work both in industry and in workshops or larger home installations. Thanks to the possibility of mounting on a panel, it provides convenient access and ease of operation. Made of high-quality plastic, it is resistant to mechanical damage and external factors. The front with an IP65 degree of protection guarantees protection against dust and water stream, allowing operation in difficult environmental conditions.

Key features and benefits

• Versatility: The ability to switch 0-Y-∆ allows adaptation to different installation needs.
• Durability: Made of high-quality materials, it ensures long-lasting and trouble-free operation.
• Safety: IP65 protection class protects against external factors, minimizing the risk of failure and injury.
• Easy installation: Designed for panel mounting, which facilitates installation and access to the device.
• Adapted to loads: The rated operating power for AC-3 is 20 kW at 400 V, allowing it to handle demanding devices.
• Solid construction: Withstands continuous current up to 63A and short-circuit current up to 1.2 kA (Icw), ensuring installation safety.
• Wide temperature range: Operation in a temperature range from -40°C to +70°C makes it suitable for use in various climatic conditions.
• Compliance with standards: Meets the requirements of EN 60947-3:1992, guaranteeing safety and reliability.

Technical parameters in practice

The continuous rated 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 of 20 kW at 400 V demonstrates its ability to effectively control electric motors with significant power. The short-circuit current value Icw at 1.2 kA indicates the device's resistance to sudden current surges during short circuits in the installation. Additionally, the screw connection of the main contacts ensures a secure and durable connection of the power supply cables.
