Cam switch connector 40A, Disconnector 0-1 (3-pole), base mounting front locking yellow/red ŁK40-2.8211\B08

Cam switch – reliable switching in your installation

This three-pole cam switch with a rated current of 40A is a solid solution for manually switching on and off electrical circuits. It will work both in industrial installations and in public buildings where reliability and safety are required. The design allows for easy switching between positions 0 and 1, making it ideal for use as a service disconnect or emergency switch.

Construction and application

The switch is designed for mounting on a panel or in an enclosure. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The IP65 protection rating guarantees protection against dust and water jets, allowing it to be used in harsh environmental conditions. Applications of the switch include:

• Disconnecting power circuits to machines and equipment
• Emergency shutdown in case of danger
• Switching control circuits
• Construction of electrical switchboards

Key features and benefits

• Durable construction: The housing made of high-quality plastic ensures long-lasting and reliable operation.
• High resistance to external conditions: IP65 protection rating protects against dust and water, allowing installation in various environments.
• Safety of use: Clear marking of positions 0-1 ensures easy and intuitive operation.
• Versatility: Possibility of mounting on a panel or in an enclosure increases application flexibility.
• Suitable for high loads: Rated continuous current of 40A and high switching power allow operation of demanding devices.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.
• Wide operating temperature range: Allows operation in the range of -40°C to +70°C, which is important in demanding industrial conditions.

Technical parameters in practice

The rated operating power for AC-3 is 20 kW at 400V, which means that the switch can safely handle devices with significant power. The short-circuit withstand current of 0.85 kA provides additional safety in the event of a short circuit. Mechanical durability of 3 million switching cycles guarantees long device life even with intensive use. The cross-section of the connection wires of 4...10 mm² allows connection of wires of different thicknesses, adapting to the needs of the installation.

The rated continuous current (Iu) is 40 A, the rated operating power AC-3 (at 400 V) is 20 kW, and the degree of protection is IP65. The number of poles is 3, and the connection of the main contacts is realized by means of a screw connection. The housing is made of plastic, and the ambient temperature during operation is in the range of -40°C to +70°C.
