Construction and application

A rotary cam switch is an element used for manual switching of electrical circuits. In this model, position 0-1 allows easy switching on and off of the power supply. The construction with screw connections ensures secure and durable wire connections. The housing made of plastic guarantees resistance to mechanical damage and corrosion, and the IP65 protection class confirms its tightness – it is dustproof and protected against water jets. The device is complete, ready for installation, which simplifies the installation process.

Key features and benefits

• Durability and reliability: Designed for frequent switching of circuits, ideal for industrial applications.
• Safety: IP65 protection class guarantees protection against moisture and dust, minimizing the risk of short circuits and failures.
• Versatility: Four-pole construction allows operation of three-phase electrical circuits.
• Easy installation: Complete device in a housing facilitates installation and saves time.
• High switching power: Rated operating power for AC-3 at 400V is 13 kW, allowing operation of devices with high power consumption.
• Durable construction: Made of high-quality materials ensures long device life.
• Clear 0-1 position: Enables intuitive operation and quick identification of the circuit status.
• Adapted to various working conditions: Wide range of ambient temperatures (-40°C to +70°C) allows operation in difficult environmental conditions.

User parameters

The rated continuous current of 25A allows safe power supply to various electrical receivers. The device is adapted to cooperate with wires with a cross-section of 2.5 mm² to 6 mm². This model has a C characteristic, which means that it copes well with starting devices with motors – allows short-term overloads without unnecessary tripping of the protection. It is worth noting the high mechanical endurance of the switch – it withstands as many as 3 million switching cycles, which guarantees long-term trouble-free operation.
