Rotary cam switch for changing the direction of rotation – reliability and versatility

This rotary cam switch, with a rated current of 63A, is a solid solution for controlling three-phase motors. Designed for rail mounting, it offers flexibility in building electrical circuits. Equipped with a red knob and a yellow-grey housing, it provides easy identification and convenient operation. Its design allows for changing the direction of rotation (L-0-P), which is particularly useful in applications requiring precise motion control.

Construction and application

The rotary cam switch SK63-3.8368\BS04 is an element used for manual switching of electrical circuits. It finds application in motor controllers, electrical switchboards and all kinds of devices requiring a change in the direction of rotation or circuit selection. Thanks to its IP65 protection rating, it is resistant to dust and water ingress, making it ideal for use in harsh industrial environments. Made of durable plastic, it ensures long-lasting and reliable operation.

Key features and benefits

• Versatility: Can be used in a wide range of applications – from simple motor controllers to advanced industrial automation systems.
• Rated operating power: Up to 18 kW for AC-3 at 400V – sufficient power for most typical industrial applications.
• Solid construction: Made of high-quality plastic, resistant to mechanical damage and chemical agents.
• Easy operation: Red knob provides convenient and intuitive operation, even with gloves.

Technical parameters – what you should know

The switch is characterized by high technical parameters, which guarantee its reliability and safety of use. The rated insulation voltage is 690 V, and the impulse withstand voltage is 6 kV. The short-circuit rated current is 1.2 kA for the 63A version and 1.5 kA for the 80A version. It is possible to connect rigid or flexible wires with a cross-section from 6 to 16 mm² for the 63A version and from 16 to 35 mm² (rigid) or from 16 to 25 mm² (flexible) for the 80A version. The switch can operate in an ambient temperature from -40°C to +70°C, which makes it suitable for harsh industrial conditions.
