Cam switch 15A, Three-phase starter switch (0,Y,A), front mounting grey knob black ŁK15-4.831\S03

Universal cam switch for extended installations

This three-phase cam switch with a rated current of 15A is a reliable solution for controlling electrical circuits. Designed for both professional and demanding users, it ensures safe and efficient operation in various conditions. Model ŁK15-4.831\S03 is distinguished by its solid construction and the possibility of mounting on a rail, which facilitates installation and servicing.

Construction and application

The cam switch allows changing the direction of rotation of three-phase motors (0-Y-∆), making it an ideal element in motor starters and applications requiring precise control. Made of durable plastic, it is resistant to mechanical damage and ensures long-term operation. The IP65 protection degree guarantees safe use even in harsh environmental conditions, protecting against dust and water spray. The possibility of indirect mounting increases installation flexibility, allowing adaptation to specific needs.

Key features and benefits

• High resistance to external conditions: The IP65 protection class makes the switch perfect for use in humid or dusty environments.
• Versatility of application: The 0-Y-∆ switch allows controlling three-phase motors in various configurations.
• Safety of use: Rated insulation voltage of 500V and impulse withstand voltage of 4kV provide protection against overvoltage and short circuits.
• Durability and reliability: Made of high-quality plastic and high mechanical durability (3 million switching cycles) guarantee long device life.
• Easy installation: Mounting method on a rail (S03) facilitates quick and trouble-free installation.
• Suitable for continuous operation: Rated continuous current of 15A allows for intensive use without the risk of overheating or damage.
• Short-circuit protection: Rated short-circuit making current of 2kA provides additional installation safety.
• Wide operating temperature range: The possibility of operation in a temperature range of -25°C to +70°C makes the device suitable for various climatic conditions.

Additional information: the switch has a black knob, and its housing is made of plastic providing good electrical insulation. The lack of auxiliary contacts (normally open and normally closed) simplifies the construction and reduces costs while maintaining the necessary control functions. The cross-section of connection wires 1.5…4 mm² allows connecting wires of different thicknesses, adapting to the requirements of a specific installation.
