Cam switch 40A, Disconnector 0-1 (2-pole), in OB2 enclosure. ŁK40-1.828\OB2

Rotary switch – reliable circuit control

This double-pole rotary switch with a rated current of 40A, housed in a durable OB2 enclosure, is a solid solution for frequent switching of electrical circuits. The design with a 0 position provides additional safety during maintenance and repairs, allowing for complete disconnection of the circuit. Designed for both professional and home use, it offers high functionality and durability.

Construction and application

Rotary switch ŁK40-1.828\OB2 is a device used for manual control of electrical circuits. Its construction based on a cam mechanism guarantees smooth and precise change of the circuit state. The OB2 housing made of plastic provides protection against external factors and a high degree of tightness (IP65), allowing for installation in conditions exposed to moisture and dust. The switch finds application in electrical installations of residential buildings, commercial buildings and in industry – wherever reliable and safe circuit control is required.

Key features and benefits

• Durable construction: The housing made of high-quality plastic provides resistance to mechanical damage and weather conditions.
• High resistance to external factors: IP65 protection rating guarantees protection against water jets and dust, allowing installation in difficult environmental conditions.
• Safety of use: Having a 0 position allows for complete disconnection of the circuit during servicing or repairs, minimizing the risk of electric shock.
• Suitable for frequent switching: The cam mechanism ensures long-lasting and reliable operation even with intensive use.
• Easy installation: Screw connection of the main contacts facilitates connection of wires, and compact dimensions allow for installation in limited space.
• Rated operating power AC-3 400V up to 20kW: Allows control of most typical electrical receivers.
• Continuous rated current 40A: Ensures safe operation with loads with high power consumption.

User parameters

The device is characterized by the lack of auxiliary contacts (normally open, normally closed and changeover), which simplifies its use in standard installations. This model is intended for direct (not indirect) mounting and is not adapted for installation in distribution boards. The knob as an actuating element provides convenient operation, and the lack of possibility to return to the 0 position after switching increases safety of use. The use of plastic as the housing material affects its lightness and electrical insulation.
