Cam switch 63A, three-phase starter switch (0,Y,A), panel mounting, yellow-grey knob, red ŁK63-4.831\P04

Cam switch – reliable switching in your installation

This three-phase cam switch with a rated current of 63A is a solid solution for disconnecting electrical circuits. Designed for panel mounting, it provides convenient and safe operation. Model ŁK63-4.831\P04 is distinguished by its versatility – it can be used in both industrial installations and workshops or service points. The construction with a yellow-gray housing and a red knob makes it easy to identify and operate.

Construction and application

The cam switch is used to manually switch electrical circuits, allowing you to change the connection configuration. In this model, we have a 0-Y-∆ starter switch, which means the ability to change the way the motor windings are connected – star (Y) or delta (∆). This is crucial for starting three-phase motors, allowing you to limit the starting current and ensure a smooth start. The plastic construction provides good insulation and resistance to mechanical damage. The IP65 protection class guarantees protection against dust and water jets, allowing operation in harsh environmental conditions.

Key features and benefits

• High mechanical resistance: Durable construction ensures long-lasting and reliable operation even with intensive use.
• Versatility: Possibility of use in various circuit configurations thanks to the 0-Y-∆ switch.
• Safety: IP65 protection class protects against external factors, minimizing the risk of failure and electric shock.
• Convenient operation: Panel mounting and clear markings make operation and identification of the switch position easier.
• Suitable for continuous operation: Rated continuous current of 63A allows for long-term operation without the risk of overheating.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +70°C makes it suitable for use in various climatic conditions.
• Compliance with standards: The product meets appropriate safety standards, guaranteeing its reliability and safety of use.

Technical parameters in practice

The rated operating power for AC-3 is 20 kW at 400 V, which means that the switch is able to handle devices with significant power. The short-circuit withstand current of 1.2 kA provides protection against the effects of short circuits. Mechanical durability of 3 million switching cycles guarantees a long service life of the device. Indirect mounting allows for flexible adaptation to various control panel structures. The lack of auxiliary contacts means that this is a solution dedicated to simple starting applications or switching circuits without the need for additional control signals.
