Cam switch disconnector 16A, switch 0-1 (3-pole), in OB4 housing with yellow/red lockable front ŁK16R-2.8211\OB4ZC

Universal cam switch for demanding applications

This three-pole cam switch 16A, with 0-1 disconnecting function, is a robust and reliable solution for switching electrical circuits. Manufactured by the renowned Spamel, model ŁK16R-2.8211\OB4ZC is perfect for both industrial installations and residential construction. The OB4 housing with a yellow-red locking front provides high resistance to mechanical damage and external factors.

Construction and application

A cam switch is a device used to manually switch electrical circuits. The cam-based design ensures smooth and reliable operation, and high mechanical strength guarantees a long service life. This model is particularly useful where frequent switching of the load or the need to disconnect the receiver from the power supply is required. Thanks to the IP65 protection class, it is resistant to dust and water ingress, allowing it to be used in harsh environmental conditions.

Key features and benefits

• High reliability: The design based on proven Spamel solutions guarantees trouble-free operation for a long time.
• Versatility: Can be used in various types of electrical installations – industrial and construction.
• Safety: IP65 protection class protects against external factors, minimizing the risk of short circuits and damage.
• Easy installation: Screw connection of the main contacts facilitates quick and secure connection of wires.
• Durability: The housing material – plastic – provides resistance to mechanical damage and corrosion.
• Suitable for frequent switching: The cam mechanism ensures smooth operation even with intensive use (mechanical durability 3 million switching cycles).
• Rated switching power AC-3 8kW: Allows operation of various receivers with significant power consumption.
• With 0 position: Allows complete disconnection of the circuit, ensuring safety during maintenance or repair.

Technical parameters in practice

The rated continuous current of 16A means that the switch can safely operate with a load of up to 16 amps for a long time. The rated operating power for AC-3 (400V) of 8 kW allows connection of devices with higher power demand. Vibration and shock resistance (compliant with IEC standards) ensures reliability even in harsh industrial conditions. The IP65 protection class guarantees protection against dust and water jet, which increases safety when used in a humid environment or outdoors (although it is not dedicated to this).
