Cam switch 63A, 1-0-2 switch (3-pole), base mounting front closure yellow/red SK63-3.8380\BS08

Cam switch – reliable circuit switching

This SK63 cam switch, designed for base rail mounting, is a solid solution for building and modernizing electrical switchboards. It enables safe and convenient switching of circuits with a rated current of up to 63A. The yellow/red front design ensures easy identification and signaling of the circuit status.

Construction and application

The SK63-3.8380\BS08 cam switch is a three-pole device (1-0-2), which means it allows you to choose between two working circuits and disconnect the power supply (position 0). It is ideal for applications requiring frequent circuit switching, e.g. in motor control systems, lighting or power supply installations for machines and equipment. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The IP65 protection class guarantees protection against dust and water jets, allowing its use in harsh environmental conditions.

Key features and benefits

• Durable construction: The housing made of high-quality plastic ensures long-lasting and reliable operation.
• High resistance to external conditions: IP65 protection class protects against dust and moisture, allowing installation in various industrial environments.
• Safety of use: Clear marking of the switch position (1-0-2) and a solid mechanical construction minimize the risk of errors and accidents.
• Easy installation: Designed for mounting on a base rail (TS35), which facilitates and speeds up installation.
• Wide range of applications: Ideal for electrical switchboards, motor control, lighting and other devices requiring frequent circuit switching.
• High switching power: The rated operating power for AC-3 is as high as 18 kW at 400V, allowing it to handle even demanding loads.
• Suitable for continuous operation: The rated continuous current Iu is 63A, ensuring stable operation even under heavy load.
• Safe connections: Screw connection of the main contacts guarantees a secure and durable connection of the wires.

Technical parameters in practice

The rated continuous current of 63A and the possibility of short-term overload (rated short-time withstand current Icw(1s) – 1.2 kA) make this switch perfectly cope with shock loads, such as starting electric motors. The switching angle of 30°-45°-90° ensures smooth and precise circuit switching. In addition, the high mechanical durability (3 million switching cycles) guarantees a long service life even with intensive use. Protection class II increases safety by isolating from grounding.
