Cam switch disconnector 40A, 0-1 (2-pole) switch, in OB2 enclosure with yellow/red sealable front ŁK40-1.828\OB2ZC

Cam switch – reliable switching in your installation

This two-pole cam switch with a rated current of 40A is a solid solution for frequent circuit switching. Designed for both professional and home use, it provides safe and convenient operation. Made of high-quality plastic, it is resistant to mechanical damage and environmental influences. Model ŁK40-1.828\OB2ZC, in OB2 housing with a yellow-red front, is distinguished by clear identification of the switch position.

Design and application

A cam switch is a device used for manual switching of electrical circuits. This model uses a cam mechanism that ensures smooth and reliable switching between the 0 and 1 positions. The OB2 housing made of durable plastic protects the internal components from dust and moisture (IP65 protection on the front side), allowing it to be used in harsh working conditions. Designed for indirect mounting, it is ideal for switchboards, control boxes and other applications requiring reliable circuit switching.

Key features and benefits

• Durability and safety: Rated current of 40A and high resistance to weather conditions guarantee long-lasting and safe operation of the device.
• Versatility: Can be used in various electrical installations – both in residential and industrial construction.
• Clear identification: Yellow-red front makes it easy to quickly identify the switch position (0-1).
• Solid construction: Made of high-quality plastic ensures resistance to mechanical damage and corrosion.
• Easy installation: Designed for indirect mounting with screws, which simplifies the installation process.
• High switching power: Rated operating power for AC-3 is as high as 20 kW at 400V, allowing it to handle even demanding loads.
• Safety of use: Rated short-circuit current withstood by the switch is 0.85 kA, providing protection against the effects of short circuits.
• Wide operating temperature range: The device retains its properties in the temperature range from -40°C to +70°C.

Technical parameters in practice

A rated continuous current of 40A means that the switch will easily handle most standard loads in electrical installations. The rated switching power of 20kW (AC-3) allows you to connect devices with significant power, such as electric heaters or electric motors. The IP65 degree of protection guarantees protection against a water jet from any direction and against the ingress of solid particles larger than 1mm – which is particularly important in humid or dusty environments. The housing material – plastic – provides good electrical insulation and resistance to chemical corrosion. Screw connection of the main contacts ensures a secure and durable connection of conductors with a cross-section from 4 to 10 mm².
