• Wide range of applications: Ideal for controlling motors, electrical switchboards and other devices requiring reliable circuit switching.

Technical parameters in practice

The rated power for AC-3 at 400 V is 3.5 kW – this means that the switch can safely handle devices with that power (e.g. electric motors). The rated continuous current Iu at 16 A determines the maximum current that can flow through the switch without risk of damage. Vibration and shock resistance (in accordance with IEC standards) guarantees stable operation even in industrial environments exposed to vibrations or accidental impacts. IP65 protection rating provides protection against dust and water jets, which is particularly important in humid or dusty rooms.

The rated power for AC-3 (400 V) is 3.5 kW. The rated continuous current (Iu) is 16 A. The protection rating (IP) is IP65. The number of poles is 3, and the type of main contact connection is screw connection.

The cam switch SK16-4.831\P23 is a solid choice for professionals and users looking for a reliable solution for controlling electrical circuits. Its versatility, durability and safety make it an ideal element of any electrical installation.
