Cam switch 20A, -2.8380 for modular installation SK20-2.8380\S10

Cam switch – reliability and durability in a compact housing

This 20A cam switch, designed for modular installation, is a solid solution for controlling electrical circuits. Designed for both demanding installers and users who value safety and convenience, it offers reliable operation in a wide range of applications. Its compact dimensions make it easy to install even in tight spaces.

Construction and application

The SK20-2.8380/S10 switch is a modular element, which means it can be easily combined with other devices to create complex control systems. It is designed for frequent switching of electrical circuits, and its robust construction guarantees long-term, trouble-free operation. It will work in industrial installations, public buildings, as well as in homes and apartments. The design allows for mounting on a TH35 rail.

Worth knowing: The cam characteristic ensures smooth switching on and off of the circuit, minimizing the risk of damage to connected devices.

Parameters and benefits

The switch is characterized by high technical parameters, which translate into its reliability and safety of use. The continuous rated current is 25A, and the rated switching current in the AC-21A/AC-22A category is 20A at voltages of 230/400/500/690V. The rated switching power in the AC-23A category reaches 10 kW at a voltage of 690V. This makes the switch suitable for controlling various electrical receivers – from lighting to electric motors.

• Mechanical endurance: Guaranteed by over 3 million switching cycles – a guarantee of long life even with intensive use.

• Wide operating temperature range: From -40°C to +70°C – enables use in difficult environmental conditions.

• High degree of protection (IP65): Provides protection against dust and water jets – ideal for use in damp or dusty rooms.

• Safety: Has CE compliance certificates and the possibility of obtaining certificates for Russia and Ukraine (information available in the documentation).

• Versatility: The possibility of mounting from 2 to 3 segments in the switch gives flexibility in the design of installations.

• Resistance to external factors: Shows resistance to vibrations, shocks and cyclic humid heat – ensures stable operation even in demanding industrial conditions.

• Wire cross-section: Accepts wires with a cross-section of 1 to 4 mm², which makes it easier to adapt to different types of installations.

The rated insulation voltage Ue is 690 V, and the impulse withstand voltage Uimp is 4 kV. The continuous rated current Iu reaches 25 A, while the rated switching current Ie in the AC-21A/AC-22A categories is 20 A at different voltages. The rated switching power P e in the AC-23A category can reach up to 10 kW at a voltage of 690 V.
