Cam switch disconnector 40A, 0-1 (3-pole), in OB3 enclosure. ŁK40-2.8211\OB3

Universal cam switch for demanding applications

This three-pole cam switch with a rated current of 40A is a reliable solution for manual switching of electrical circuits. It is suitable for both industrial installations and applications requiring frequent load switching. The design with a 0 position provides additional safety and ease of use.

Solid construction and high protection

The switch is housed in a robust OB3 enclosure made of plastic, which guarantees resistance to mechanical damage and external factors. The IP65 protection rating provides protection against water jets and dust, allowing operation in harsh environmental conditions. Screw connection of the main contacts ensures a secure and durable connection of the wires.

Key features and benefits

• Suitable for working with various loads: Rated power up to 20 kW at 400V (AC-3) allows for use in a wide range of applications.
• Safety first: It has a 0 position, which allows for complete isolation of the circuit during maintenance or repair.
• Durability and reliability: Made of high-quality materials, ensuring long life and resistance to wear. Mechanical durability is as high as 3 million switching cycles.
• Resistance to external conditions: The enclosure with IP65 protection protects against moisture and dust, allowing operation in demanding industrial conditions.
• Simple installation: Designed for indirect mounting, which facilitates integration with existing electrical infrastructure.
• Versatility: Ideal for switching electric motors, transformers and other devices requiring manual control.
• Clarity: The knob as an actuator provides intuitive operation and easy control of the device.

Parameters for professionals

The rated continuous current Iu is 40A, and the rated short-circuit current Icm is 1.5kA – these parameters guarantee safe operation of the device even under high loads. The tightening torque of the terminals is 2.0 Nm, which ensures a stable connection of wires with a cross-section from 4 to 10 mm². The switch meets safety standards and has appropriate certificates of conformity (see manufacturer's documentation). The rated insulation voltage Ui is 690V and the impulse withstand voltage Uimp is 6kV.
