Cam switch 40A, Disconnector 1-0-2 (4-pole), base rail mounting front yellow-grey knob red SK40-4.8396\BS04

Universal cam switch for various applications

This four-pole cam switch, with a rated current of 40A, is a reliable solution for switching electrical circuits. The 1-0-2 (disconnect) design allows you to choose between two working positions and an off position, making it ideal for applications requiring flexibility and safety. TH35 rail mounting ensures easy installation in distribution boards and control cabinets.

Solid construction and high resistance

The housing made of durable plastic guarantees durability and resistance to mechanical damage. The IP65 protection class provides protection against dust and water spray, enabling use in harsh environmental conditions. The switch is designed to operate in a wide temperature range, from -40°C to +70°C, making it suitable for industrial and commercial applications. Mechanical endurance of 3 million switching cycles ensures long-lasting and trouble-free operation.

Key features for professionals and end users

• Versatility: Possibility of indirect mounting and mounting on TH35 rail simplifies integration with existing installations.
• Safety: IP65 protection class protects against environmental influences, minimizing the risk of failure.
• Efficiency: Rated power for AC-3 is 12 kW at 400V, allowing you to handle various loads.
• Durability: Made of high-quality materials and high resistance to weather conditions ensure long service life.
• Adaptation to different loads: Continuous rated current at 40A and conventional short-circuit current of 10kA allow for safe use in various applications.
• Ease of use: Red knob provides intuitive operation and quick identification of the switch status.
• Compliance with standards: Meets safety and reliability requirements, ensuring compliance with applicable regulations.

Technical parameters in practice

The rated switching power in AC-23A category is 9 kW at 230V and as much as 26 kW at 690V – this shows its ability to handle both smaller and larger loads. The short-time thermal current of 0.5 kA demonstrates its resistance to momentary overloads. The possibility of connecting cables with a cross-section from 4 to 10 mm² provides flexibility when selecting appropriate cables. The tightening torque of the terminals of 1.2 Nm guarantees a secure electrical connection.
