Cam switch 15A, Three-phase starter switch (0,Y,A), with yellow-red front panel IP41 ŁK15-4.831\P02

Cam switch for extended installations

This three-phase cam switch with a rated current of 15A is a reliable element for controlling electrical circuits. Model ŁK15-4.831\P02, equipped with a yellow-red front and IP41 protection degree, performs well in applications requiring frequent switching of loads. The plastic construction provides good insulation and resistance to mechanical damage.

Construction and application

The cam switch is designed for indirect mounting, which provides flexibility in choosing the installation location. Designed to work with a rated insulation voltage of 500V and impulse voltage of 4kV, it guarantees safe use. The use of screw connections facilitates the connection of wires, and the ability to configure with a different number of segments (up to 16) allows it to be adapted to specific installation needs. This is particularly useful in industrial applications where control over multiple circuits is required simultaneously.

Key features and benefits

• Versatility: The ability to choose from many segment configurations (from 1 to 16) allows you to adapt the switch to different applications and user needs.
• Durability: A continuous rated current of 15A and high mechanical durability (3 million switching cycles) ensure long-lasting and reliable operation of the device.
• Safety: The IP41 protection degree protects against accidental contact and the ingress of solid objects larger than 1mm, which increases safety. Additionally, the rated insulation voltage of 500V provides adequate protection against electric shock.
• Easy installation: Screw connections facilitate and speed up the process of connecting wires, which translates into time savings during installation.
• Application: Ideal for starting three-phase motors (0-Y-∆ configuration), changing the direction of rotation and other applications requiring frequent switching of loads.
• Solid construction: Made of plastic, it provides resistance to corrosion and mechanical damage, which extends the life of the device.

Operating parameters

The rated operating power for AC-3 at 400V is 8kW, which demonstrates its capabilities in controlling larger loads. The short-time withstand current Icw(1s) is 0.5kA and the short-circuit making capacity Icm is 2kA - these parameters indicate the ability to withstand temporary overloads and short circuits. The cross-section of the connection wires is 1.5…4 mm², which ensures compatibility with most standard electrical installations. The ambient operating temperature is from -25°C to +70°C, which allows it to be used in various environmental conditions.
