Technical Parameters in Practice

The SK40-7.8538\P03 switch is characterized by high technical parameters that translate into its reliability and efficiency:

The rated operating power (AC-3) is 12 kW – allows controlling motors with high power in industrial applications. The continuous rated current is 40 A, which ensures stable operation even under heavy load. The IP65 protection rating guarantees reliable operation in harsh conditions, protecting against dust and water. The number of poles is 2, which is a standard configuration for most motor applications, and the housing material – plastic – provides light weight and structural strength.

Additionally, the lack of auxiliary contacts makes the switch simpler to operate and more reliable – fewer elements mean a lower risk of failure. Screw connection type ensures a secure connection of wires, eliminating the risk of loosening connections during operation.
