3TBI AC Contactor
Applications:
The contactor is suitable for using in the circuits up to the rated voltage 660V AC 50Hz or 60Hz, rated current 630A, for making and breaking, and for frequent starting and controlling the motor. After combined with the mechanical interlocking device, it becomes 3TD Series convertible contactor for controlling, starting, breaking and reversing of the motor. The products comply with IEC60947-4.

Key Specifications/Special Features:
3TB Series AC contactor
Applications:
3TF series AC contactor are suitable in electrical system with AC 50/60Hz, rated operational voltage up to 660V
In AC-3 usage, rated operational voltage up to 380V, rated operational current up to 630A to make or break remote motors or system
They form electromagnetic starters with suitable thermal overload or phase-failure
Made according to IEC 60947, BS 5424 & VDE 0660
Contactor is straight motion mechanism having double breaking contacts
Auxiliary contacts are arranged NO.2NC at most, it is employed flexible locking connection between contact support and core, three are no arc-isolated panel in Ie≤22A contactor
In the In≥32A contactors, three are molded arc-chute with arc-isolated panel, because all contacts are made of high con-fusibility and against corrosion silver alloy
All series products can be mounted by screw, Ie≤32A contactor also by installation rail
