Universal cam switch for demanding applications

This three-pole cam switch with a rated current of 63A is a solid solution for both professional installers and end users. Designed for electrical circuits with a power of up to 20 kW (AC-3, 400V), it provides reliable switching and disconnection of the load. The construction in an OB3 enclosure with a lockable front (yellow/red) guarantees high resistance to external conditions and safe use.

Construction and application

The cam switch LK63-2.8211\OB3ZC is a device used for manual switching of electrical circuits. It finds application in industrial, construction installations and in control systems, where reliable disconnection and connection of the load is required. Designed for indirect mounting, it allows for flexible adaptation to specific installation needs. Made of durable plastic, it provides durability and resistance to mechanical damage. The lockable front increases safety, minimizing the risk of accidental contact with live parts.

Key features and benefits

• High resistance to external factors: IP65 protection rating provides protection against dust and water jets, allowing the switch to be used in harsh environmental conditions.
• High switching power: Rated operating power up to 20 kW (AC-3, 400 V) allows operation of even demanding receivers.
• Safe use: Lockable front minimizes the risk of accidental contact with live parts.
• Durable construction: The housing made of high-quality plastic ensures long-lasting and reliable operation of the device.
• Flexible mounting: Indirect mounting option makes it easy to adapt the switch to different installation configurations.
• Suitable for frequent switching: Mechanical durability of 3 million switching cycles guarantees long life even with intensive use.
• Safety in case of short circuits: Short-time withstand current Icw(1s) is 1.2 kA, and short-circuit making current Icm is 2.2 kA – this ensures effective protection of the installation in the event of a short circuit.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +70°C makes the switch usable in various climatic conditions.
