Cam switch 40A, Disconnector 1-0-2 (2-pole), in OB13 enclosure with yellow/red lockable front and indicator lamp SK40-2.8338\OB13ZC/L

Rotary switch – reliable circuit control

This 2-pole rotary switch SK40, combined with the OB13 housing and a lockable front (yellow/red with indicator light), is a robust solution for frequent circuit switching. Designed for both professional applications and end-users requiring reliability and safety. The lockable front provides additional protection against accidental access to live parts.

Characteristics and application

The SK40 rotary switch is a device used for manual switching of electrical circuits. It finds application in industrial installations, machines, heating devices and anywhere where frequent and reliable load control is required. This model, with a rated current of 40A, is perfect for circuits with medium power. The 1-0-2 switch allows you to choose between two different circuit configurations, increasing its functionality.

Key features and benefits

• Durability and reliability: Continuous rated current of 50A and high resistance to external conditions (ambient temperature from -40°C to +70°C) guarantee long-lasting and trouble-free operation.
• Safety: IP65 protection class provides protection against dust and water jets, which is particularly important in harsh industrial conditions. The OB13 housing further increases safety.
• Versatility: Possibility of mounting on a panel (□48 hole) and a wide range of connection wire cross-sections (4…10 mm²) facilitate installation and integration with existing systems.
• High mechanical durability: Withstands up to 3 million switching cycles, which translates to a long service life even with intensive use.
• Wide voltage range: Rated insulation voltage of 690V and impulse withstand voltage of 4kV ensure safe operation in various electrical installations.
• Status indication: The presence of an indicator light facilitates visual control of the switch status, increasing operating safety.

The continuous rated current is 50A, allowing for safe loading of the switch. The rated switching current is 40A at different voltages (230/400/500/690 V). The rated insulation voltage reaches 690V, and the impulse withstand voltage 4kV – providing a high level of safety. The IP65 protection class guarantees resistance to dust and water, and the possibility of connecting wires with a cross-section of 4 to 10 mm² facilitates installation.

The SK40 rotary switch is an investment in reliable and safe control of electrical circuits. Solid construction, high quality workmanship and compliance with standards ensure long-lasting and trouble-free operation.
