Overview
Rockwell Automation has produced quality Medium Voltage products to meet the requirements
of all types of industries for well over six decades.
From the original oil-immersed contactor to air break and vacuum contactors, to solid-state controllers
such as Smart Motor Controllers and AC Variable Frequency Drives, Rockwell Automation has
developed and built a medium voltage product line that satisfies industries who are demanding more
safety, less maintenance, longer life and reliability in motor control equipment.
Added to those demands is the need for smaller, more flexible medium voltage products that are more
efficient and reduce building and expansion costs.
OEM frames and components leverage the existing family of motor controllers built by Rockwell
Automation. They also incorporate some of the most fundamental, high volume components available
in our OEM product line for Original Equipment Manufacturers and electrical equipment companies.
Bulletin 1502 vacuum contactors are a comprehensive line of vacuum contactors used as isolating
contactors or as bypass contactors. Light weight and maintainability are but two of the features of this
fixed-mounted design.
Bulletin 1503F OEM components are a series of medium voltage frame-mounted components
designed to mount into new or existing structures or enclosures. These assemblies can also be
used to retrofit existing motor controllers. These products are available as a complete OEM frame or
sold individually as components.
Bulletin 1503E MV SMC™ Flex OEM kits are a series of solid-state reduced voltage components
designed to mount into new or existing structures or enclosures. These assemblies can also be used to
retrofit existing motor controllers. These products are available as an OEM frame and components.
Bulletin 1901 SyncPro™ is a field application and protection system for squirrel-cage, brush-type
synchronous motors.
Rockwell Automation also offers standard motor controllers, solid-state reduced voltage starters,
and variable speed drives with standard, yet flexible, product configurations for all product lines.
Rockwell Automation offers several OEM programs, such as customer-specific program
(custom engineered options and configurations with a standard quick-ship delivery). Contact your local
Rockwell Automation office for more information on these programs and other OEM products.

A contactor drop-out delay may be configured with the IntelliVAC control module (refer to publication 0-UM0_-EN-P).
The full altitude range is available with the IntelliVAC control module only, and the IntelliVAC is to be configured accordingly (refer to
publication 0-UM0_-EN-P). The standard mechanical latch contactors, if used with electro-mechanical control, are designed
for -000 to 000 meters (-00 to 00 feet). Higher altitudes are possible by changing the contactor return spring.
Altitude adjustment (manual) is required to support full altitude range.
The number of contactor auxiliary contacts depends on the contactor type. Some of the contactors are used in the typical control
schemes used.
Series D contactors are suitable for electro-mechanical (relay) control only.

INTELLIVAC™ CONTROL MODULE FOR MV VACUUM CONTACTORS
Advanced Digital Control of Vacuum Contactors
The Allen-Bradley Bulletin 1503VC IntelliVAC™ control module offers a superior and efficient means of
controlling Bulletin 1502 vacuum contactors. The same controller is used for both 400 and 800 A vacuum
contactors, as well as both electrically held or mechanically latched contactors.
IntelliVAC™ Control Module
• The IntelliVAC™ control module is available with a universal input voltage
(110 - 240 V AC, 50/60 Hz or 110-250 V DC)
• Consistent vacuum contactor pick-up time
• Selectable and repeatable vacuum contactor drop-out times for better coordination with power fuses
• Altitude compensation (-1,000 to 5,000 meters)
IntelliVAC™
• Power loss ride-through (TDUV) allowing the vacuum contactor to remain closed during brief power
loss (up to 2 sec.)
• Anti-kiss and anti-pumping protection
• Temporary motor jog function
• Status indication
• Delayed restart
The IntelliVAC controller is offered as a substitute for electro-mechanical control circuits with numerous
additional benefits (see pages 12 and 40). OEMs have a more flexible means of unit control that results
in reduced overall panel space and enhanced control functionality.
Each IntelliVAC module comes with all required “quick connect” style connectors. A wire harness is
required to connect the module to Bulletin 1502 vacuum contactors (see page 6).
Control Power Selector Assembly
A selector switch and power receptacle are provided to allow “Normal”, “Off” and “Test” sources of control
power for the IntelliVAC control Module. A 115 V AC receptacle, suitable for use in North America, is
provided as part of the 1503C-CPS1.

Description
Bulletin 1502 contactors are available for use as bypass contactors. They are required to bypass or
short out the SCRs once the motor is up to speed. The SMC Flex control module will control the closing
of this contactor when the auxiliary contact is programmed for the up-to-speed setting.
Bulletin 1502 contactors (fast dropout only) are used with the 800 to 6900 V AC frames and power
poles. Select the appropriate current, line voltage and control voltage to suit your application.
Note: The SCRs must be bypassed once up to speed. They are not rated for continuous duty.
Failure to bypass the SCRs will result in component failure.
