Cam switch 25A, Voltage Measurement Switch, in OB2 enclosure. ŁK25R-4.883\OB2

Universal cam switch for demanding applications

This 25A cam switch, in a robust OB2 housing, is a reliable solution for switching electrical circuits. Designed for both industrial and building installations, it ensures safe and efficient operation. This model, number 4.883, is particularly useful as a voltage measurement switch, allowing convenient monitoring of network parameters.

Construction and application

The switch is made of high-quality plastic, guaranteeing its durability and resistance to mechanical damage. The IP65 protection rating provides protection against dust and water jets – an ideal solution for environments with increased humidity or dust. The voltage measurement switch allows for easy and precise reading of voltage values in the circuit, which is crucial in the diagnostics and maintenance of electrical installations. Screw connection ensures a secure and stable connection of wires.

Key features and benefits

• Durable construction: The housing made of plastic provides resistance to damage and long device life.
• High resistance to external conditions: IP65 protection rating guarantees safe use in harsh environmental conditions.
• Intended as a voltage measurement switch: Allows convenient monitoring of electrical network parameters.
• High rated power: The rated power for AC-3 is 13 kW at 400 V, allowing operation of demanding loads.
• Safety of use: Rated continuous current of 25 A and high short-circuit resistance (conventional short-circuit current 13 kA) ensure safe operation of the installation.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +70°C makes the switch suitable for use in various climatic conditions.
• Versatility: Availability of different segment configurations (from 1 to 15) allows adaptation of the switch to individual installation needs.
• Mechanical durability: Withstands up to 3 million switching cycles, guaranteeing long-term and reliable operation.

Technical parameters in practice

The rated continuous current of 25A means that the switch will easily handle most standard loads in residential and industrial buildings. The high value of the conventional short-circuit current (13kA) guarantees safety in the event of a short circuit – the device will withstand a sudden increase in current without damage. This protects the installation from serious failures and downtime. The cross-section of connection wires 2.5...6 mm² provides flexibility in choosing the appropriate cables for a specific application.
