Cam switch 16A, Disconnector 0-1 (3-pole), in OB4 enclosure. ŁK16R-2.8211\OB4

Rotary switch – reliable switching in your installation

This three-pole rotary switch with a rated current of 16A is a solid solution for frequent circuit switching. Equipped with a "0" position, it provides full control over the power supply and additional safety. The OB4 housing, made of durable plastic, guarantees resistance to mechanical damage and external factors. Ideal for both industrial applications and public buildings where reliability and durability are required.

Design and application

The rotary switch from the ŁK16R series is a component designed for manual switching of electrical circuits. This model, in the version with OB4 housing, offers a high degree of protection IP65, which makes it resistant to dust and water – it can be used even in difficult environmental conditions. The switch with a knob allows for convenient and precise operation. The rated operating power for AC-3 is 8 kW at 400V, which allows for operation of various receivers. Screw connection of the main contacts ensures secure and durable connection of the wires.

Advantages and product features

• High reliability: Construction based on proven solutions guarantees long-lasting and trouble-free operation.
• Durable housing: The plastic of the OB4 housing provides protection against mechanical damage and external influences.
• IP65 protection: Ensures resistance to dust and water, allowing installation in difficult conditions.
• "0" position: Additional protection against accidental circuit activation during maintenance or repair.
• Versatility: Suitable for a wide range of applications – from industrial installations to public buildings.
• Designed for frequent switching: Mechanical endurance of 3 million switching cycles ensures long life even with intensive use.
• Safety: Rated conditional short-circuit current of 13 kA provides effective protection of the installation in the event of a short circuit.
• Easy installation: Screw connection of the main contacts facilitates connection of the wires.

Technical parameters in practice

Rated continuous current of 16A means that the switch can safely handle devices drawing this current for a long time. Rated power of 8 kW at 400V allows controlling motors with a power of up to 8 kW (in category AC-3). Vibration and shock resistance (compliant with IEC standards) confirms its suitability in demanding industrial conditions. Wide operating temperature range (-40°C to +70°C) allows its use both indoors and outdoors (with appropriate protection against atmospheric factors). Connection wire cross-section of 1.5…4 mm² ensures compatibility with most standard electrical installations.
