B Series

B Series

contactor-b-1
Application

  • B series AC Contactors are mainly used in 50/60Hz electrical lines of the rated voltageup to 660V AC and rated current up to 370A, are applicable for remote making and breaking ofelectrical lines or frequent control of AC motors, having no-voltage protection. .
  • Usually, it can becombined with JR29(T) series thermal relay to form electromagnetic starters which have overloadand open-phase protection.
  • It complies with IEC947-4-1.
