Cam switch connector 25A, Disconnector 0-1 (4-pole), in OB4 housing with yellow/red front. ŁK25R-2.8210\OB4C

Cam switch – reliable switching in your installation

This 4-pole cam switch with a rated current of 25A is a solid solution for frequent circuit switching. It finds application in both industrial installations and commercial and residential construction, where reliability and safety are required. Model ŁK25R-2.8210\OB4, enclosed in a durable OB4 housing with a clear yellow/red front, ensures easy identification and intuitive operation.

Construction and application

A cam switch is a device used for manual switching of electrical circuits. In this model, thanks to the 0 position, it is possible to completely disconnect the load, which increases safety during maintenance or repair. The construction with screw connections guarantees secure and durable wire connections. The housing made of plastic provides insulation and protection against external factors. The IP65 degree of protection confirms resistance to dust and water jets, allowing the switch to be used in harsh environmental conditions.

Key features and benefits

• High mechanical resistance: The robust construction allows for a large number of switching cycles (3 million), which translates into a long service life.
• Safety of use: The 0 position allows for complete disconnection of the load, minimizing the risk of electric shock during maintenance work.
• Versatility: Suitable for controlling various types of loads, including electric motors (rated operating power for AC-3 up to 13 kW at 400V).
• Easy installation: Designed for indirect mounting (although it does not require it), and screw connections facilitate the connection of wires with a cross-section of 2.5…6 mm².
• Protection against weather conditions: The IP65 degree of protection guarantees safe operation in humid and dusty environments.
• Clear identification: The yellow/red front makes it easy to quickly identify the switch in the installation.

Technical parameters and compliance with standards

The switch meets stringent safety and quality standards. The rated continuous current is 25A, and the short-circuit withstand current is 13 kA, ensuring effective protection of the electrical installation. The device has CE, RU and UA certificates of conformity, confirming its safety and approval for use in Europe and neighboring countries. The rated insulation voltage U_i is 690V and the rated impulse withstand voltage U_imp is 6kV. Additionally, the device is characterized by high resistance to vibrations and mechanical shocks in accordance with IEC standards.
