Cam switch 63A, Disconnector 0-1 (4-pole), in OB3 housing with yellow/red front ŁK63-2.8210\OB3C

Cam switch – reliable switching in your installation

This four-pole cam switch with a rated current of 63A is a solid solution for switching electrical circuits on and off. Equipped with a 0-1 disconnector, it allows for safe isolation of the load, which is crucial during maintenance or repair. The OB3 enclosure design provides high resistance to environmental and mechanical conditions, and the yellow-red front makes identification easier.

Construction and application

A cam switch is a versatile device used in low-voltage electrical installations. It can function as a switch, disconnector, changeover switch or control switch. The segmented structure with double cams allows for the creation of various connection programs, tailored to the specific needs of the application. Designed for use in enclosed spaces, it withstands harsh industrial conditions thanks to a wide operating temperature range (-40°C to +70°C). Thanks to the screw connection, installation is simple and quick.

Key features and benefits

• High resistance: The plastic housing and IP65 protection rating guarantee protection against dust and moisture, which translates into a long service life of the device.
• Safety of use: Rated continuous current of 63A and high short-circuit strength (1.2 kA) ensure safe operation of the installation.
• Versatility: The ability to configure the cam angle (30°, 45° or 90°) allows the switch to be adapted to different applications.
• Durability: Tested for vibration, shock, damp heat and salt mist – meets the requirements of PN-EN60947-3 and IEC 60947-3 standards.
• Easy installation: Screw connection of the main contacts facilitates and speeds up installation.
• Mechanical strength: Ensured by 3 million switching cycles.
• Rated power AC-3: 20 kW at 400 V – suitable for most industrial and commercial applications.

This cam switch is an investment in the reliability and safety of your electrical installation. It will work well in both new projects and in the modernization of existing systems.
