B Series AC Contactors
|
|
|||||
| B series AC contactors, 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 elctrical line or frequent control of AC motors, haveing 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. |
