Cam switch disconnector 25A, 0-1 switch (3-pole), in OB4 enclosure with lockable front ŁK25R-2.8211\OB4Z

Universal cam switch for safe circuit switching

This three-pole 25A cam switch, in a robust sealed housing, is a reliable element of electrical installation. Designed for both professional and domestic applications, it provides safe and convenient circuit switching. Model ŁK25R-2.8211\OB4Z from Spamel is distinguished by its high quality and resistance to external conditions.

Features and application

The cam switch is used to manually switch electrical circuits, allowing you to choose between different power sources or disconnect the load. The design with a "0" position allows for complete disconnection of the circuit, increasing safety. The housing with an IP65 protection class protects against dust and moisture, making it an ideal solution for workshops, garages, and industrial environments. Screw connection ensures a secure and durable connection of the wires.

Advantages in practice

• Durable construction: The housing made of plastic provides resistance to mechanical damage and corrosion.
• Safety of use: The "0" position allows for complete disconnection of the circuit, minimizing the risk of electric shock.
• Protection against external conditions: IP65 protection class guarantees tightness against dust and water, allowing the switch to be used in difficult conditions.
• Easy installation: Designed for indirect mounting (although not required), which simplifies installation in various configurations.
• High switching power: Rated power of 13 kW at 400V allows operation of demanding electrical receivers.
• Suitable for continuous operation: Rated continuous current of 25A ensures stable operation even under heavy load.
• Versatility: Suitable for a wide range of applications – from home installations to industrial power systems.

Technical parameters in the context of application

The switch is characterized by high strength parameters – short-circuit withstand current at the level of 1 kA and short-circuit switching current 1.4 kA testify to its reliability in emergency situations. Mechanical durability of 3 million switching cycles guarantees long device life even with intensive use. The cross-section of connection wires 2.5...6 mm² ensures compatibility with most standard electrical installations. Rated insulation voltage Ui is 690V and impulse withstand voltage Uimp is 6kV - which confirms its safety in demanding working conditions.
