Disconnect switch 40A, Disconnector 0-1 (1-pole), front mounting grey knob black ŁK40-1.825\S03

Cam switch – reliable switching in your installation

This single-pole cam switch, with a rated current of 40A, is a solid solution for frequent circuit switching. Designed for rail mounting, it offers convenience and safety during installation and use. Equipped with a black knob and a gray housing, it combines functionality with aesthetics. Ideal for use in electrical switchboards where reliability and ease of operation are required.

Construction and application

Cam switch ŁK40-1.825\S03 is an element designed for manual switching of electrical circuits. Its construction based on a cam mechanism ensures a secure and stable connection. The switch with 0-1 position allows for complete disconnection of the circuit, which increases safety during maintenance or repair. Front rail mounting facilitates installation and removal, and the IP65 protection rating guarantees resistance to dust and moisture – even in harsh working conditions.

Advantages and benefits

• Durability and reliability: Made of high-quality plastic, it ensures long-term, trouble-free operation.
• Safety: It has a 0 position, allowing for complete disconnection of the circuit, which is crucial during maintenance work.
• Easy installation: The front rail mounting design significantly speeds up installation and reduces labor costs.
• Resistance to external conditions: IP65 protection rating protects against dust and moisture, allowing it to be used in various environments.
• Wide range of applications: Suitable for circuits with a rated power of up to 20 kW (for AC-3 at 400V), making it a universal solution for many electrical installations.
• Adapted to work in difficult conditions: A wide range of ambient temperatures (-40°C to +70°C) allows it to be used in demanding industrial applications.
• Solid connections: Screw connection ensures a secure and durable connection of wires with a cross-section from 4 mm² to 10 mm².

Technical parameters in practice

The rated continuous current of 40A and high short-circuit resistance (Icm = 1.5 kA) make this switch suitable even for loads with a variable character. The rated insulation voltage Ui of 690V ensures safety in high-voltage installations. Mechanical durability of 3 million switching cycles guarantees long device life even with intensive use. It is also worth noting the resistance to vibrations and shocks – the switch has been tested according to IEC standards, which confirms its reliability in harsh industrial conditions.
