Cam switch 40A, Disconnector 1-0-2 (6-pole), front mounting grey knob black ŁK40-6.8380\S03

Universal cam switch for safe circuit switching

This six-pole cam switch LK40-6.8380\S03 is a reliable solution for manual switching of electrical circuits. Designed for both industrial and building installations, it offers high functionality and safety. The design allows for rail mounting, making it easy to integrate with existing distribution systems. Made of durable plastic, it ensures long-lasting and trouble-free operation.

Construction and application

The cam switch with position 0 (1-0-2) allows disconnection of the circuit in the middle position, which increases safety during maintenance or repair. It is designed to operate at a rated insulation voltage of 690V and a continuous current of 40A, making it suitable for a wide range of applications. The use of screw connections ensures secure and durable connections of wires with a cross-section of 4…10 mm². The IP65 protection class guarantees protection against dust and water jets, allowing installation in harsh environmental conditions.

• Versatility: Ideal for switching circuits powering various types of receivers, such as motors, heaters or lighting.
• Safety: Position 0 allows complete disconnection of the circuit during maintenance or repair work.
• Durability: Made of high-quality materials, it ensures long-lasting and reliable operation even in demanding conditions.
• Easy installation: The design intended for mounting on a DIN rail simplifies and speeds up installation.
• Protection: IP65 protection class protects against external factors such as dust and moisture.
• High power: The rated operating power for AC-3 is 20 kW (at 400V), allowing operation of devices with high power consumption.
• Adapted to work in difficult conditions: A wide range of operating temperatures (-40…+70°C) allows use in various industrial and construction environments.

User and construction parameters

The switch is characterized by high mechanical and electrical resistance, confirmed by numerous tests and certificates. Mechanical endurance at 3 million switching cycles guarantees long-term trouble-free operation. The housing material - plastic - provides insulation and corrosion resistance. Additionally, this model has a high rated short-circuit current Icm of 1.5 kA and a rated short-time withstand current Icw(1s) of 0.85 kA, which translates to greater safety of the electrical installation. The design with a knob facilitates operation even with work gloves, and the gray finish of the housing is aesthetic and practical.
