Product Description

Scope

This User Manual applies to the Allen-Bradley, Bulletin 1502 (Series D),
400 A electrically held vacuum contactors, designed for applications in the
2400 to 7200 volt range.

Contactor Description

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 (3) vacuum interrupters (hereafter referred to as
vacuum bottles) operated by an electromagnet assembly through a
mechanical linkage. They are resistant to most 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 electrically held vacuum contactors are available in 120-volt
and 230-volt control configurations. Mechanically latched contactors are
only available in 120-volt control configurations.
