Cam switch 20A, Switch 1-0-2 (3-pole), base rail mounting front grey knob black SK20-3.8380\BS23

Cam switch – reliable circuit switching

This three-pole cam switch SK20-3.8380\BS23 is a solid solution for frequent switching of electrical circuits. Designed for both professional and home use, it combines durability, safety and ease of use. The construction with position 0 provides additional safety during maintenance and repairs. Mounting on a TH35 rail guarantees quick and secure placement in the distribution cabinet.

Construction and application

The cam switch is used to manually switch electrical circuits, allowing you to choose from three positions: 0 (off), 1 and 2. It is ideal for controlling devices requiring frequent changes in direction of rotation, such as electric motors, heaters or lighting. Made of high-quality plastic, it provides good insulation and resistance to mechanical damage. The gray front with a black knob makes it easy to identify and operate. The IP65 degree of protection guarantees protection against dust and water jets, allowing use in harsh environmental conditions.

Key features and benefits

• Durability and reliability: Designed to operate with a continuous rated current of 20A and a short-circuit current of 10kA, it ensures safe operation of the electrical installation.
• Versatility: The possibility of mounting on a TH35 rail facilitates installation in distribution cabinets and allows for quick adaptation to various installation configurations.
• Safety: It has a "0" position allowing complete disconnection of the circuit during maintenance or repair.
• Mechanical durability: Withstands up to 3 million switching cycles, guaranteeing long-term and trouble-free operation.
• Protection against external influences: IP65 protection class protects against dust and water, enabling use in demanding environmental conditions.
• Universality: Suitable for both professional (industrial installations, workshops) and home use (garages, home workshops).
• Ease of use: The ergonomic knob makes it easy to switch circuits even with work gloves.
• Compliance with standards: Ensures safe operation of the electrical installation in accordance with applicable standards.

User parameters

The rated power for AC-3 is 4 kW at 400V, making it suitable for many industrial and home applications. The housing material made of plastic provides good electrical insulation and resistance to mechanical damage. The lack of auxiliary contacts makes it a simple solution for basic switching applications. The switch is adapted for indirect mounting, which gives flexibility in choosing the installation location.
