Cam switch disconnector 25A, 0-1 switch (3-pole), in OB2 housing with yellow/red sealable front. ŁK25-2.8211\OB2ZC

Cam switch 25A in enclosure – reliable switching in your installation

This three-pole cam switch with a rated current of 25A, enclosed in a durable OB2 housing, is a solid solution for frequent circuit switching. The device, designated as a disconnect switch 0-1, finds application in both industrial installations and public buildings. The yellow-red front cover provides additional identification and safety.

Design and application

A cam switch is an element used to manually switch electrical circuits on and off. The ŁK25R-2.8211\OB2 model is distinguished by its high mechanical and electrical resistance, which guarantees long-term and trouble-free operation. The OB2 housing protects the internal components from external factors such as dust, moisture and mechanical damage (IP65 protection). This makes the device suitable for use even in harsh environmental conditions.

The design of the switch allows for mounting on a plate or in distribution boards. It is designed to operate at temperatures from -40°C to +70°C, making it a universal solution for various applications. The cross-section of the connection cables 2.5…6 mm² ensures compatibility with most standard installations.

Parameters and benefits for professionals

The switch is characterized by a continuous rated current of 25A, allowing for the safe switching on of devices with significant power consumption. The rated insulation voltage is 690V, providing a high level of safety. The rated switching power (AC-3) is 7 kW at 230V, 13 kW at 400V and 10 kW at 690V – enabling control of various energy consumers. Mechanical durability at 3 million switching cycles guarantees a long service life even with intensive use, and IP65 protection ensures resistance to water jet and dust – ideal for use in demanding environmental conditions. The torque for tightening the terminals is 1.2 Nm, ensuring a secure connection of the cables.

For installers, this means easy installation, reliable operation and compliance with applicable safety standards. The solid construction and high quality of workmanship translate into minimal maintenance requirements and long-term customer satisfaction.

Additional technical information

The rated short-circuit current is 13 kA, and the short-time withstand current is 1 kA. The device meets the standards for vibration resistance (IEC 60068-2-6) and shock resistance (IEC 60068-2-27). The number of segments in the switch can be up to 4 (depending on the model), and the actuator is a knob.

The device meets safety requirements and has appropriate certificates (CE, RU, UA). Downloadable files are available: data sheets, operating instructions and declarations of conformity on the manufacturer's website Spamel.
