Cam switch 40A, Disconnector 1-0-2 (1-pole), base mounting rail front grey knob black SK40-1.834\BS03

Cam switch – reliable disconnection in your installation

This cam switch with a rated current of 40A is a solid solution for safe and convenient disconnection of electrical circuits. Equipped with a 1-0-2 mechanism (1 - pole), it enables effective circuit isolation in three positions: open, off and closed. Front panel mounting, combined with a gray housing and black knob, ensures an aesthetic appearance and easy integration with existing infrastructure.

Design and application

The cam switch SK40-1.834\BS03 is designed for a wide range of applications – from industrial installations to commercial and domestic buildings. Its robust plastic construction guarantees long-lasting and reliable operation even in harsh conditions. The IP65 protection class provides resistance to dust and moisture, making it an ideal choice for environments exposed to adverse external factors. The cam mechanism allows for quick and reliable switching of circuits, minimizing the risk of errors and downtime.

Key features and benefits

• High reliability: Continuous rated current of 40A and short-circuit rated current of 1.2 kA ensure safe operation even under heavy loads.
• Universal mounting: Indirect mounting option simplifies installation in various configurations.
• Mechanical durability: Designed for intensive use – withstands up to 3 million switching cycles.
• Safety of use: IP65 protection class protects against moisture and dust, increasing work safety.
• Wide range of applications: Ideal for industrial installations, commercial buildings and homes.
• Easy operation: The knob allows for intuitive operation of the device.
• Rated operating power for AC-3, 400 V: 12 kW – allows connection of devices with significant power.
• Resistance to environmental conditions: Wide operating temperature range (-40°C to +70°C) ensures reliability in various conditions.

Technical parameters in practice

This switch not only meets safety standards (rated insulation voltage 690V), but also offers practical solutions for installers. For example, the ability to connect cables with a cross-section of 6-16 mm² provides flexibility in choosing the appropriate cables. The lack of auxiliary contacts (both normally open and normally closed) simplifies the connection diagram, and the inability to return to the "0" position eliminates the risk of accidental disconnection of the circuit during operation. The solid plastic construction ensures durability and resistance to mechanical damage.
