Cam switch disconnector 25A, 0-1 (3-pole) with signal path, in OB3 enclosure. ŁK25R-2.829\OB3

Rotary switch – reliable switching in your installation

This three-pole rotary switch with a rated current of 25A is a solid solution for frequent switching of electrical circuits. Equipped with a 0 position, it provides additional safety and control over the installation. Model ŁK25R-2.829\OB3, enclosed in a durable OB3 plastic housing, is resistant to mechanical damage and ensures long-term reliability.

Functionality and application

The rotary switch finds wide application in electrical installations of residential, commercial buildings and in industry. It is ideal for situations where manual switching of circuits is required, e.g. when changing the power source, servicing equipment or in control systems. Thanks to the possibility of indirect mounting, it can be easily adapted to different configurations of switchboards and control cabinets. In addition, the IP65 protection class guarantees safe use even in harsh environmental conditions – it protects against dust and water spray.

Key features and benefits

• Durable construction: The housing made of high-quality plastic provides resistance to mechanical damage and corrosion.
• Safe operation: It has a 0 position, which allows for complete disconnection of the circuit during maintenance or repair.
• Universal mounting: The possibility of indirect mounting makes installation easier in different types of switchboards.
• Resistance to external conditions: The IP65 protection class guarantees tightness against dust and water, enabling operation in difficult conditions.
• High efficiency: The rated operating power for AC-3 is 13 kW at 400 V, allowing it to handle demanding receivers.
• Suitable for frequent switching: Mechanical endurance of 3 million switching cycles ensures long-term reliability even with intensive use.
• Safe connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.

Technical parameters in practice

The rated continuous current of 25A allows for safe power supply to various electrical devices. The rated switching power (7 kW at 230V and 13 kW at 400V) demonstrates the ability to handle both standard household appliances and more demanding industrial equipment. Additionally, high resistance to vibration and shock (compliant with IEC 60068-2-6 and IEC 60068-2-27 standards) guarantees stable operation even in environments with high levels of mechanical interference. The conventional short-circuit current of 13kA provides effective protection of the installation in the event of a short circuit.
