Cam switch 63A, three-phase starter switch (0,Y,A), front panel mounting closed black SK63-4.831\P07

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 SK63-4.831\P07 is distinguished by its versatility – it can be used in industrial installations, workshops, and service points. The lockable design (P07 version) further enhances security and protects against unauthorized access.

Construction and application

The SK63 cam switch is a device used for manual switching of electrical circuits. The 0-Y-∆ (delta) version is particularly useful in applications related to the starting of three-phase motors, allowing you to change the winding configuration to optimize the starting and operating parameters of the motor. The design for panel mounting provides easy access and intuitive operation. The housing made of plastic guarantees mechanical strength and resistance to external factors. The IP65 protection class on the front side provides protection against water jets and dust, making it ideal for use in harsh environmental conditions.

Key features and benefits

• High mechanical resistance: Durable plastic construction ensures long-lasting and reliable operation.
• Safety of use: Lockable housing (P07 version) minimizes the risk of accidental or unauthorized switching on/off of the circuit.
• Versatility: Indirect mounting option allows for flexible adaptation of the switch to different installation configurations.
• Resistance to external conditions: IP65 protection guarantees the tightness of the housing, protecting against moisture and dust.
• Suitable for high loads: Rated continuous current of 63A and the ability to switch loads up to 18 kW (AC-3, 400V) make the switch perfect for demanding industrial applications.
• Easy installation: Screw connection of the main contacts facilitates cable connection and ensures a secure electrical connection.
• Wide range of applications: Ideal for disconnecting motors, controlling lighting, and other electrical devices requiring manual circuit switching.

Technical parameters in practice

The switch is characterized by high mechanical durability – it withstands up to 3 million switching cycles, guaranteeing years of trouble-free operation. It is designed to operate in a wide range of ambient temperatures (-40°C to +70°C), making it suitable for use both indoors and outdoors (provided adequate protection against atmospheric factors). The rated short-circuit current of 1.2 kA provides effective protection of the installation in the event of a short circuit. The ability to connect cables with a cross-section from 6 mm² to 16 mm² provides flexibility when choosing the appropriate power cables.
