ProSense Motor Control Relays ... New!
AutomationDirect offers three types of monitor relays for motor control:
- Phase monitor relays provide protection against premature
equipment failure caused by voltage faults on 3-Phase systems. All
ProSense 3 phase monitor relays are designed to be compatible with
typical Wye or Delta systems. Phase monitoring relays protect against
single phasing regardless of any regenerative voltages.
- Alternating relays are used for motor load control in special applications where the
optimization of load usage is required by equalizing the run time of
two loads. The alternating action is initiated by a control switch, such
as a float switch, manual switch, timing delay, pressure switch, or
other isolated contact. Each time the initiating switch is opened, the
output relay contacts will change state, thus alternating the two loads.
- Pump failure relays are designed to monitor the shaft seals of
submersible pumps. A resistive-measuring probe provided by the pump manufacturer is installed in the
pump seal cavity. If the pump seal starts to leak, contaminating fluid enters
the seal cavity, lowering the resistance between the internal probe
and the common connection. When the resistance drops below
the user-adjustable sensitivity setpoint of the relay, the output relay energizes.

Fuji Motor Contactors and Overload Relays
AutomationDirect has cooperated with Fuji Electric to offer a complete line of IEC electric motor controls.
- The DUO line (SC-E contactors and TK-E overloads) is fully integrated so multiple motor speed controller solutions are possible with a minimum number of components.
The conventional motor starters in the DUO line can accommodate electric motors up to 100 horsepower at 480VAC. The larger motor contactors feature the SUPERMAGNET™ coil for greater reliability and positive pick-up and drop-out.
New! ... 440-480 VAC and 500-550 VAC Coil Voltages
- The Odyssey Series of contactors and overload relays also features the SUPERMAGNET™ coil and come in sizes up to 361 A, AC-3 operation (300 horsepower at 480 VAC). Odyssey Series contactors are available in four sizes with overload relays to match any motor to 300 horsepower.
New! ... 380-450 VAC and 460-575 VAC Coil Voltages
- Both the DUO and Odyssey lines are available in 24 VAC, 24 VDC, 120 VAC, 240 VAC, 380-575 VAC. The motor contactors are rated up to 690 VAC, 3-phase.

Fuji Manual Motor Starters
The Fuji Duo Series Manual Motor Starter is a protective device for electric motor use that
provides optimal protection by integrating the functions of a molded
case circuit breaker and thermal overload relay into a compact
unit. Since Fuji’s MMS is UL listed for Category E self-protected
motor control, it can be used for motor branch circuit protection
without the need for additional protection such as fuses or molded
case circuit breakers.
- The Manual Motor Starter is available in a 32A version with
a 45mm frame width, and a 63A version with a 55 mm frame
width.
- Both MMS versions have high breaking capacities, up to
100,000A in some ranges. A wide range of accessories is available,
including shunt trips and undervoltage releases.

Eaton Cutler-Hammer Contactors / Motor Starters / Overload Relays
Cutler-Hammer’s Freedom series of IEC contactors feature a compact space saving design. Components that meet IEC 60947 are more reliable, of higher quality, and are better matched to their intended application.
- The Cutler-Hammer CE15 Freedom
Series IEC contactors offer big contactor
ratings in a compact frame. The 45 mm
frame contactors can handle up to 20 hp
at 460V. They are easily DIN-rail mountable
in either the vertical or horizontal
upright position.
- The Cutler-Hammer AE16 Series IEC
starters are full voltage magnetic starters
used for starting polyphase induction
motors. These motor starters also provide
protection to the motor against running or
stalled overcurrents. The 45 mm frame starters can handle up
to 20 hp at 460V. They are easily DIN-rail
mountable in either the vertical or horizontal
upright position.
Motor starters are comprised of a contactor,
overload relay and heater packs. The
overload relays have FLA adjustable dials.

GH Series Contactors / Motor Starters / Overload Relays
The GH series of IEC contactors and bimetallic
overload relays are manufactured
by Europe’s leading maritime contactor
company. Contactors for ocean-going
vessels are built to the most rigid specifications.
This same design technology carries
over to this line of industrial electric motor controls.
- We offer individual components that allow
you to use the contactor alone or to
assemble your motor starter using our
thermal overload relays. You can also
combine a manual motor starter/protector
for all-in-one protection.
- Use contactors wherever you need a
heavy-duty switching device with up to
three poles. Add up to eight auxiliary
contact blocks for interlocks and feedback.
Or, use the optional mechanical interlock
to create an inexpensive reversing
contactor.

AC Motor Soft Starters ... New!
STELLAR™ SR22 semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors. The SR22 motor soft starters use thyristors for controlled reduced voltage motor starting and stopping. These low voltage soft starters then switch to internal contacts for efficient running at the rated speed
