Cam switch 20A, Disconnector 0-1 (2-pole), in OB11 enclosure. SK20-1.828\OB11

Universal cam switch for low voltage circuits

This two-pole cam switch, combined with a robust OB11 housing, is a reliable solution for switching currents in electrical installations. It is suitable for both industrial and residential applications where frequent circuit state changes are required. The design with double cams allows for flexible creation of connection programs tailored to the specific needs of the installation.

Construction and application

The cam switch SK20-1.828\OB11 is designed for operation in enclosed spaces, in conditions with temperatures ranging from -40°C to +70°C. The OB11 housing made of PA6 plastic provides protection against mechanical damage and external factors (IP65 protection class). This makes the switch resistant to dust and moisture, increasing its durability and safety. It can be used as a switch, disconnector, changeover switch or control switch in low voltage electrical circuits.

Key features and benefits

• Durable construction: The switch is designed for intensive use, with a mechanism withstanding up to 3 million switching cycles.
• Versatility: Possibility of configuring the connection program thanks to the segmented structure and different knob pitch angles (every 30°, 45° or 90°).
• Safety: IP65 housing protects against accidental contact with conductive elements and protects against the effects of moisture and dust.
• Easy installation: Screw connection of the main contacts facilitates the connection of wires with a cross-section from 1 mm² to 4 mm².
• Compliance with standards: Meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, guaranteeing safety and reliability.
• High rated power: The rated continuous current is 20A, and the switching capacity reaches 4 kW (AC-3 at 400V), allowing for use in various applications.
• Resistance to environmental conditions: Withstands vibrations, shocks, temperature changes and salt mist – confirmed by tests in accordance with IEC standards.

This switch is a solid solution for both professionals involved in electrical installations and end-users looking for a reliable element for their home installations. Its versatility and high quality of workmanship guarantee long-lasting and safe use.
