Cam switch 40A, 1-0-2 switch (1-pole), front panel mounting, enclosed, yellow/red ŁK40-1.834\P08

Cam switch – reliable circuit switching

This cam switch, with a rated current of 40A, is a solid solution for switching electrical circuits. Designed for both professional and demanding users, it provides safe and convenient operation. The design with a yellow-red closed front ensures good visibility of the switch status and increased protection against moisture and dust (IP65). This model is ideal for mounting on panels or in enclosures.

Functionality and application

The cam switch with position 0 (1-0-2) allows disconnection of the circuit in position "0", which increases safety during maintenance or repair. Designed for indirect mounting, it offers flexibility in choosing the installation location. The rated operating power for AC-3 is 20 kW at 400V, making it suitable for controlling various loads. Made of plastic, it is resistant to mechanical damage and environmental factors.

Key features and benefits

• Durability and reliability: Continuous rated current of 40A guarantees stable operation even under heavy load.
• Safety: The "0" position allows complete disconnection of the circuit, minimizing the risk of electric shock during service work.
• Versatility: Indirect mounting allows adaptation to different installation configurations.
• Protection: IP65 protection class provides resistance to dust and water ingress, which is particularly important in harsh working conditions.
• Durability: The housing material – plastic – provides resistance to corrosion and mechanical damage.
• Easy operation: The knob made of high-quality materials ensures convenient and precise switching.
• Wide range of applications: Suitable for controlling motors, heaters and other electrical devices requiring frequent circuit switching.
• Designed for intensive use: Mechanical endurance of 3 million switching cycles guarantees long-term use without the need for replacement.

Technical parameters in practice

The rated continuous current Iu at 40A means that the switch can safely operate with a load of that intensity for a long time without overheating. The rated switching power P e in category AC-3 of 20 kW (at 400 V) indicates its ability to effectively control electric motors of appropriate power. The short-time withstand current I cw(1s) of 0.85 kA indicates its resistance to short-term current surges that may occur when switching on high-power devices. The tightening torque of the terminals of 2.0 Nm ensures a secure connection of the wires, minimizing the risk of loosening connections during operation.
