Cam switch 40A, 1-0-2 switch (3-pole), in OB2 enclosure. SK40-3.8380\OB2

Cam switches – reliable switching in your installation

This 40A rated cam switch is a solid solution for disconnecting electrical circuits. The 1-0-2 (3-pole) design provides versatility, allowing you to choose between different connection configurations. Mounting in an OB2 enclosure further increases the safety and durability of the device, protecting it from external factors.

Construction and application

The SK40-3.8380\OB2 cam switch is designed for frequent switching of electrical circuits, both in industrial installations and commercial construction. Its robust construction and high resistance to environmental conditions guarantee reliable operation for a long time. The cam mechanism ensures secure and precise switching on and off of the circuit. Thanks to the possibility of mounting on a panel or in an enclosure, the device is easy to integrate with existing infrastructure.

Key features and benefits

• Durability and reliability: Designed to operate in harsh conditions, with high resistance to vibration and shock.
• Versatility: 1-0-2 design allows for flexible adaptation to different installation needs.
• Safety: OB2 enclosure provides protection against moisture, dust and accidental contact with live parts (IP65 protection rating with respect to the panel).
• Wide range of applications: Ideal for motor disconnectors, power source switches and other applications requiring frequent circuit switching.
• Compatibility: Possibility to connect cables with a cross-section from 16 to 35 mm², both rigid and flexible.
• Mechanical durability: Withstands up to 3 million switching cycles, guaranteeing long device life.
• Compliance with standards: Meets the requirements of PN-EN 60529 and EN 60947-1 standards, ensuring safe use.

Technical parameters in practice

The switch is characterized by a rated insulation voltage Ue of 690V and a rated continuous current Iu of 80A. The short-circuit withstand current Icw(1s) is 1.5kA, providing additional safety in the event of a short circuit. A wide operating temperature range (-40°C to +70°C) allows it to be used in various environmental conditions. Protection class II increases safety by isolating from ground.
