Cam switch 40A, -4.8240 in OB3 enclosure with yellow/red locking front ŁK40-4.8240\OB3ZC

Cam switch – reliable switching in your installation

This 7-pole cam switch with a rated current of 40A, housed in a robust OB3 enclosure with a yellow-red locking front, is a solid solution for circuit switching. The knob design ensures convenient and precise operation, and the high IP65 protection rating guarantees safety in harsh industrial conditions. It is suitable for applications requiring frequent switching, as well as where protection against moisture and dust is critical.

Construction and application

A cam switch is a device used to manually switch electrical circuits. In this model, the combination of a cam and 7 poles allows for the implementation of complex switching sequences. The OB3 enclosure made of plastic provides insulation and protection against mechanical damage. The locking front increases the seal, and the yellow-red color scheme facilitates identification and signaling of the device status. It is ideally suited for controlling motors, heaters and other devices requiring reliable switching of electrical circuits.

Key features and benefits

• High resistance to external conditions: IP65 protection rating protects against dust and water ingress, making it an ideal solution for indoor and outdoor applications.
• High rated power: Rated power for AC-3 at 20 kW allows operation of demanding loads.
• Safe use: Made of high-quality plastic ensures insulation and minimizes the risk of electric shock.
• Durable construction: The material of the housing and solid screw connections guarantee a long service life of the device.
• Versatile application: 7 poles allow configuration for various installation needs.
• Easy installation: No need to use additional cable glands (depending on the configuration) simplifies the installation process.
• Designed for continuous operation: Rated continuous current of 40A ensures stable operation of the device for a long time.
• Position 0: The presence of the "0" position allows for complete disconnection of the circuit, providing additional safety during maintenance or repair.

Technical parameters in practice

The use of a screw connection of the main contacts ensures a secure and durable connection of the wires. The lack of normally open or normally closed auxiliary contacts simplifies the design and reduces costs, while fulfilling the basic switching functions. This model is not intended for indirect mounting or installation in distribution boards – it has been designed as a complete device in an OB3 housing, ready for direct mounting. Mechanical endurance of 3 million switching cycles guarantees long-term reliability even with intensive use.
