63A Cam Switch, Three-phase direction of rotation reversing starter switch, panel mounting front grey knob black SK63-5.8538\P03

Motor Starter Switch – Reliable Motor Control

This three-phase cam switch with a 63A current rating is a robust solution for disconnecting and reversing the direction of rotation of motors. Panel mounting provides convenient operation, and the gray housing with a black knob looks aesthetically pleasing in any workshop or production hall. The device is particularly useful in applications requiring frequent changes in direction of rotation, such as construction machinery, conveyors, or industrial equipment.

Functionality and Safety

The switch is designed with safety and reliability in mind. The IP65 protection rating guarantees resistance to dust and water jets, allowing operation in harsh industrial conditions. The plastic construction provides good electrical insulation, and the screw connection of the main contacts enables secure and durable connection of wires. Additionally, the presence of a "0" position allows for safe disconnection of the circuit.

• Versatility: Designed for disconnecting motor circuits and switching the direction of rotation.
• Durability: Continuous rated current of 63A and high resistance to environmental conditions.
• Safety: IP65 protection rating protects against moisture and dust, and the "0" position ensures safe disconnection.
• Mounting: Quick and easy panel mounting thanks to dedicated design (P03).
• Compliance with standards: Meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards, guaranteeing high quality and safety of use.
• Rated power: Rated operating power for AC-3 is 18 kW at 400V, making it suitable for most industrial applications.
• Flexibility: Possibility of indirect mounting increases the range of applications.

Technical Parameters in Practice

This cam switch is not just a set of technical parameters – it is a practical tool for installers and end-users. A continuous rated current of 63A means that the device can handle most standard three-phase motors used in industry. A rated operating power of 18 kW at 400V allows for controlling even larger loads. Additionally, the lack of auxiliary contacts (normally closed, normally open and changeover) simplifies installation and reduces the risk of errors during connection. The construction allows operation in temperatures from -40°C to +70°C, making it ideal for outdoor or harsh environmental applications.
