Establish and cut off the supply of a downstream installation from an electrical control characterised a rated voltage of Ue, a rated current Ie, a control circuit voltage Uc, with Np poles, in the Industrial application areas, according to the appropriate use scenario, and during the reference service life of the product of 20 years. Ue = Rated voltage (V): 600 Ie = Rated current (A): 720 Uc = Control circuit voltage (V): 24 Np = No. of poles: 3 Load rate = 50% of In Use time rate = 50% Category of use = AC53a
