Product Description
The Cutler-Hammer
®
Intelligent
Technologies (IT.) Electro-Mechanical
Contactor from Eaton’s electrical
business consists of an IT. Electro-
Mechanical Contact Block and IT.
Electro-Mechanical Coil Controller as a
Full Voltage Non-reversing (FVNR) or
Full Voltage Reversing (FVR) device.
Size 00 to Size 4 Contact Blocks
combined with Coil Controllers (factory
or field assembled) are stand-alone
Contactors. Only the Size 5 Contactors
have internal factory assembled coil
controllers.
Features
■ Size 00 – 5, 9 – 270A, 2 – 200 hp,
600V
■ 24V DC Coil Control — safe, reliable
global standard
■ Frame width (mm): 45, 54, 76, 105,
140
■ No laminations, shading coils or
magnet noise
■ -40 to 149°F (-40 to 65°C)
operating temperature
■ No seal in auxiliary contacts
required — control wiring is not
needed between the contactor and
overload relay
■ Conformal coated printed circuit
boards for resistance to harsh
environments
■ Unique Pulse Width Modulated coil
controller minimizes coil power
consumption
■ Microprocessor-based control
■ Easily accessible mounting feet for
panel mounting

Contacts: 1NO, 1 NC, 2NO, 2NC,
1NO/1NC and logic level
■ 2- or 3-wire control
■ Built-in logic to provide either 2- or
3-wire control, eliminating the need
to provide and wire auxiliary con-
tacts to seal in and interlock the
contactor coils

wiring — plug and unplug lockable
control connector
■ DIN rail mounting for Sizes 00 – 2
■ Optional mounting plates for
Size 00 – 4
■ Common accessories
■ Long-life silver nickel and silver tin
oxide contacts provide excellent
conductivity and superior resistance
to welding and arc erosion
■ Environmentally friendly materials
■ Low wattage coils and minimal heat
dissipation
Reversing Contactors
■ Includes Reversing Power Wiring
and bus bars
■ Mounting plates for Size 00 – 4
