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 electrical line or frequent control of AC motors,
have 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. |
