B series AC contactors are mainly used in 50/60HZ electrical lines of the rated voltage up to 660V AC and rated current up to 475A, are applicable for remote making and breaking of electrical lines or frequent control of AC motors, having no-voltage protection. Usually, it can be combined with T series thermal relay to form electromagnetic starters, which have overload and open-phase protection. It complies with IEC947 & VDE0660.
