Cam switch 40A, circuit switch 0-1-2-3, in OB2 enclosure. SK40-2.8445\OB2

Cam switch – reliable circuit switching

The cam switch SK40, in OB2 housing, is a solid and versatile device designed for safe and efficient switching of electrical circuits. The design based on a cam mechanism ensures high reliability and durability, making it an ideal solution for both professional installers and end users. This model, with a rated current of 40A, is perfect for applications requiring frequent load switching.

Construction and application

This cam switch allows switching between circuits 0-1-2-3, making it a versatile tool in many electrical installations. It finds application in controlling electric motors, electrical switchboards, and in power supply systems for machines and equipment. The robust construction and high resistance to environmental conditions guarantee long-term and trouble-free operation. Panel mounting (requires a 68mm diameter hole) is simple and intuitive.

Key features and benefits

• High mechanical resistance: Durable cam mechanism ensures a long service life of the device – up to 3 million switching cycles.
• Wide voltage range: Suitable for operation in networks with a rated insulation voltage of up to 690V and an impulse withstand voltage of up to 6kV.
• Adapted to various conditions: Possibility of operation at temperatures from -40°C to +70°C and high resistance to vibrations and shocks.
• Safe to use: Protection class IP65 (in OB2 housing) protects against external factors such as dust and moisture. Protection class II provides additional safety for users.
• Flexible mounting: Possibility of panel mounting with a 68mm diameter hole facilitates integration with existing installations.
• Adapted to wires of different thicknesses: Possibility of connecting rigid wires with a cross-section of 16-35 mm² and flexible wires with a cross-section of 16-25 mm².
• Provides effective protection: Short-circuit withstand current at the rated level of 1.5kA and rated switching impulse withstand current 1.6kA provide protection against the effects of overloads and short circuits.
