Cam connector 25A, -6.821 in OB3 housing. ŁK25R-6.821\OB3

Cam switch – reliable switching in your installation

This 25A cam switch in an OB3 housing is a solid and functional solution for switching electrical circuits. Designed for both professional and demanding users, it ensures safe and efficient operation. The plastic housing guarantees durability and resistance to mechanical damage, and the IP65 protection rating protects against environmental influences.

Construction and application

A cam switch is a device used to manually switch electrical circuits. The ŁK25R-6.821 model with an OB3 housing is characterized by a rated current of 25A and the ability to operate with a load of up to 13 kW in AC-3 configuration. It finds application in electrical installations of public buildings, industrial plants, as well as in workshops and homes, wherever reliable and manual circuit control is required. Four poles allow switching of both phase, neutral and auxiliary wires.

Key features and benefits

• Durable construction: The plastic housing provides resistance to mechanical damage and weather conditions.
• High resistance to external factors: IP65 protection rating guarantees protection against dust and water jets – ideal for industrial or humid environments.
• Safety of use: Rated operating power up to 13 kW (400 V) and high continuous rated current of 25A ensure safe operation of the device with various loads.
• Easy installation: Indirect mounting option simplifies installation in various configurations.
• Suitable for frequent use: Mechanical durability of 3 million switching cycles guarantees long device life even with intensive use.
• Precise switching: Cam mechanism ensures smooth and reliable circuit switching.
• Versatility: Lack of auxiliary contacts allows for simple integration with existing control systems.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.

Technical parameters in practice

Rated operating power of 13 kW for AC-3 means that the switch will easily handle typical industrial equipment, such as medium-power electric motors. The rated short-circuit current of 13 kA indicates high resistance to overloads and short circuits, which translates into installation safety. A wide operating temperature range (-40°C to +70°C) allows the switch to be used in harsh environmental conditions. The possibility of connecting wires with a cross-section of 2.5…6 mm² ensures compatibility with most standard electrical installations.
