Cam switch connector 25A, 1-0-2 switch (2-pole), for modular installation SK25-2.8338\S10

Modular installation changeover switches – reliable circuit switching

This two-pole changeover switch SK25-2.8338\S10 is a solid solution for controlling electrical circuits, both in professional and home installations. Designed for modular mounting, it provides convenience and flexibility in building switchboards. The design allows switching between three positions: 0-1-2, making it ideal for applications requiring selection of a power source or disconnection of a load.

Construction and application

The SK25 changeover switch is an element used for manual switching of electrical circuits. It finds application in electrical installations of residential buildings, commercial buildings and in control cabinets. Thanks to the possibility of selecting positions 0-1-2, it allows for flexible load control – from complete disconnection (position 0), through power supply from one source (position 1), to selection of another source (position 2). Made of durable plastic, it ensures durability and resistance to mechanical damage.

Features and benefits

• High reliability: Rated continuous current at 25A guarantees safe operation even under heavy loads.
• Versatility: Possibility of indirect mounting allows adaptation of the switch to different installation conditions.
• Safety: Protection class IP65 protects against dust and water, which increases safety in difficult environmental conditions.
• Durability: Made of high-quality plastic ensures long device life.
• Flexibility: Three switching positions (0-1-2) allow for a wide range of applications – from simple on/off to power source selection.
• Easy installation: Screw connection of the main contacts facilitates and speeds up the installation process.
• Rated power for AC-3: Up to 8 kW at 400V – allows controlling motors and other devices with higher power consumption.

User parameters

The switch is characterized by a solid construction and high technical parameters, which translate into its reliability and long life. Designed to operate in ambient temperature from -40°C to +70°C, it is resistant to extreme weather conditions. In addition, high resistance to mechanical shocks (15g) ensures its stable operation even in the event of vibrations or sudden movements. The cross-section of connection wires 1...4 mm² allows connection of wires of different thicknesses, which increases the flexibility of the installation. Tightening torque of the terminals is 0.5 Nm, which ensures a secure connection of the wires without the risk of damage.
