Product Description
Contactor Description The Allen-Bradley, Bulletin 1502, 400 A vacuum contactors are designed for
applications in the 2400 and 7200V range. The contactor is suitable for all types
of AC loads, for example: three-phase motors, transformers, power capacitors
and resistive heating loads.
The contactor uses three interrupters (hereafter referred to as vacuum bottles)
operated by an electromagnet assembly through a mechanical linkage. They are
resistant to adverse atmospheric conditions and provide long mechanical and
electrical life.
The contactors are utilized in various starter and drive configurations, for
example: full-voltage non-reversing, full-voltage reversing, two-speed, reduced
voltage, synchronous, drive input/output and bypass applications. They are
generally fixed mounted within the structures and the line and load terminations
are made at the rear of the device. In most configurations, the main contactor is
mechanically interlocked with the external operating handle and isolating switch.
Bulletin 1502 vacuum contactors are designed for use with the IntelliVAC and
IntelliVAC Plus control module (refer to Publication
1503-UM053_-EN-P
and 1503-UM054_-EN-P ). The mechanical latch contactor may also be applied
with an electromechanical (relay) control panel.
Bulletin 1502 electrically held and mechanical latch vacuum contactors are
provided with coils rated for 108 VDC. The IntelliVAC and IntelliVAC Plus control
module can accept a wide array of supply voltages for maximum flexibility (refer to
Publication
1503-UM053_-EN-P and 1503-UM054_-EN-P ).
