Cam switch 25A, Circuit switch 0-1-2-3, in OB2 enclosure. ŁK25-2.8445\OB2

Universal cam switch for demanding applications

This 25A cam switch, in OB2 housing, is a reliable solution for controlling electrical circuits. Designed for use in industrial and construction installations, it provides safe and efficient circuit switching. The design allows configuration as a 0-1-2-3 circuit switch, making it a versatile element in many applications.

Construction and application

A cam switch is a mechanical device used to connect and disconnect electrical circuits. In this model, housed in a robust OB2 housing, it is particularly resistant to mechanical damage and environmental factors. It finds application as a switch, disconnector, switch or control switch in low-voltage installations. The segmented design with double cams allows for the creation of connection programs tailored to specific needs – the angle of rotation of the knob can be 30°, 45° or 90°. This allows even complex switching sequences to be implemented.

Key features and benefits

• Durability and reliability: The OB2 housing made of plastic provides protection against mechanical damage and external influences.
• Wide operating temperature range: The device maintains its properties in a temperature range from -40°C to +70°C, allowing it to be used in harsh industrial conditions.
• Compliance with standards: Meets the requirements of PN-EN60947-3 and IEC 60947-3, guaranteeing safety and compliance with applicable regulations. It also meets standards for resistance to vibration, shock, damp heat and salt mist (IEC 60068-2-6, IEC 60068-2-27, IEC 60068-2-30, IEC 60068-2-52).
• High resistance to environmental conditions: Designed for indoor use in environments with a degree of pollution of 3 (industrial application).
• Versatility: The ability to configure as a 0-1-2-3 circuit switch increases the range of applications.
• Safety: Rated continuous current of 25A and high short-circuit strength (13 kA) ensure effective protection of the electrical installation.
• Easy installation: Available in a version for mounting in an enclosure (OB2), which facilitates integration with existing systems.
• Durability: Mechanical durability of 3 million switching cycles guarantees a long service life.

The rated continuous current is 25A, the rated switching power AC-3 (400 V) is 13 kW, and the rated conventional short-circuit current reaches 13 kA.

This cam switch is a solid and reliable solution for professionals and users looking for high-quality components for electrical installations. Its versatility and durability make it an investment for years to come.
