Cam switch disconnector 25A, 0-1 (3-pole), in OB2 enclosure. ŁK25-2.8211\OB2

Cam switch – reliable switching in your installation

This 25A cam switch, with 0-1 disconnector and three poles, enclosed in a durable OB2 housing, is a solid solution for controlling electrical circuits. Designed for both industrial and building installations, it provides safe and efficient load switching. The device's construction guarantees long-lasting and trouble-free operation even in harsh conditions.

Features and application

Spamel cam switch is an element used for manual switching of electrical circuits. Model ŁK25R-2.8211\OB2 is particularly useful wherever reliability and frequent switching are required. It finds application in:

• Electrical switchboards – as a control element for individual circuits.
• Machines and equipment – for switching on and off the power supply to individual components.
• Lighting installations – allows changing the lighting configuration.
• Industrial applications – where high resistance to environmental conditions is required.

Product advantages

• Durable construction: OB2 housing provides protection against mechanical damage and external factors (IP65 protection).
• Safety of use: Rated insulation voltage Ui 690V and impulse withstand voltage Uimp 6kV guarantee safe operation of the device.
• Wide range of applications: Rated current of 25A allows for servicing various loads.
• Simple installation: The switch is adapted for easy mounting on a plate or in a distribution board.
• Durability: Made of high-quality materials, ensures long service life (3 million switching cycles).
• Versatility: Possibility of use in various working environments (ambient temperature from -40°C to +70°C).

Technical parameters in practice

The rated switching power Pe for AC-3 is 7 kW at 230V, 13 kW at 400V and 10 kW at 690V – which means that this switch can easily handle typical electrical devices found in industry and construction. The rated short-circuit making current at 13 kA provides additional safety for the installation in the event of a short circuit. The cross-section of connection wires from 2.5 mm² to 6 mm² provides flexibility when connecting different types of wires. It is also worth paying attention to the tightening torque of the terminals of 1.2 Nm – correct tightening ensures a stable electrical connection and minimizes the risk of overheating.
