Cam switch 16A, Disconnector 0-1 (3-pole), in OB11 housing with yellow/red lockable front SK16-2.8211\OB11ZC

Rotary switch 16A in enclosure – reliable circuit control

This three-pole rotary switch, enclosed in a durable OB11 housing, is a solid solution for frequent switching of electrical circuits. Designed for both industrial and building installations, it provides safe and efficient control. Model SK16-2.8211\OB11ZC stands out for its high quality and compliance with applicable standards.

Construction and application

Rotary switches of the SK series are rotating devices, ideal for switching currents on and off in low-voltage circuits. They are used as isolators, disconnectors, switches and control switches. The design with double cams allows for the creation of various connection programs, tailored to the specific needs of the installation. The OB11 housing provides protection against external factors, and the IP65 degree of protection guarantees resistance to dust and moisture – which is particularly important in harsh working conditions.

Key features and benefits

• Durable construction: The housing made of PA6 plastic ensures durability and resistance to mechanical damage.
• Safety of use: The IP65 degree of protection protects against access to live parts and environmental influences.
• Versatility: Possibility of mounting on a plate or directly on the surface.
• High efficiency: Rated continuous current of 16A and rated operating power of 3.5 kW (AC-3, 400V) allow for servicing various receivers.
• Easy installation: Screw connection of the main contacts facilitates and speeds up installation.
• Compliance with standards: Meets the requirements of PN-EN60947-3 and IEC 60947-3, which guarantees safety and reliability.
• Wide operating temperature range: The device can operate at temperatures from -40°C to +70°C, making it suitable for use in various climatic conditions.
• Resistance to external factors: Exhibits resistance to vibrations, shocks, damp heat and salt mist in accordance with IEC standards.

Technical parameters in practice

Rated continuous current of 16A means that the switch can safely operate with a load of up to 16 amps for a long time without the risk of overheating or damage. Rated operating power of 3.5 kW at 400V indicates its ability to handle devices of this power – e.g. electric motors or heaters. The IP65 degree of protection provides protection against a water jet from any direction and against access to dangerous live parts – which is crucial for the safety of installers and end users. The housing material (plastic) provides light weight and ease of installation, as well as resistance to chemical corrosion.
