Cam switch 40A, Three-phase reversing starter switch, panel mount, gray front, black knob SK40-5.8538\P03

Rotary switch – reliable control of electrical circuits

This three-pole rotary switch with a rated current of 40A is a solid solution for manual switching of circuits on and off. Designed for panel mounting, with an IP65 front, it provides safe and convenient operation even in harsh industrial conditions. The knob design allows for precise control, and the ability to change the direction of rotation expands the range of applications.

Construction and application

The SK40-5.8538\P03 rotary switch from SPAMEL is a device designed for manual control of electrical circuits. It is ideal for applications requiring frequent switching, such as switching on electric motors, controlling lighting, or in automation systems. Made of durable plastic, it ensures long-lasting and reliable operation. The IP65 protection rating guarantees resistance to dust and water ingress, making it suitable for use indoors and outdoors.

Key features:

• Three-pole design: allows control of three phases simultaneously, which is essential in many industrial applications.
• Rated current 40A: ensures safe operation with loads up to 12 kW (AC-3).
• Changeover capability: expands the functionality of the switch, allowing control of devices requiring a change in direction of operation.
• IP65 protection rating: guarantees resistance to dust and water ingress, ensuring safe operation in harsh conditions.
• Panel mounting: facilitates integration with existing installations and control panels.
• Durable plastic: provides resistance to mechanical damage and corrosion.
• With 0 position: additional safety thanks to the ability to switch off the circuit in the zero position.

Technical parameters and user benefits

This rotary switch is characterized by high technical parameters, which translate into its reliability and durability: the rated operating power for AC-3 is 12 kW at 400 V, and the continuous rated current is 40 A. Made of high-quality materials and with a solid construction, it ensures a long service life even with intensive use. Screw connection of the main contacts guarantees a secure connection of the wires, minimizing the risk of short circuits and failures. Additionally, the lack of a need to return to the 0 position increases ease of use – the off position can be maintained without additional pressure. The rated insulation voltage Ui is 690V and the impulse voltage Uimp 6kV, which ensures a high level of safety.
