Lighting Contactors
Lighting contactors are the safe, convenient and efficient means for local or remote switching of tungsten
(incandescent filament), ballast (fluorescent and mercury arc), or high intensity discharge (HID) lighting loads.
Definite Purpose
Definite purpose contactors and starters are electrically operated switching devices specifically designed
for the heating, ventilation, air conditioning and refrigeration (HVACR) industry. They are typically controlled
by automatic (i.e. thermostat) control or manual (i.e. pushbutton) interfaces.
Land Transportation
Land Transportation contactors, starters and remote power transfer switches are designed to meet the demanding
shock, vibration, and temperature requirements of locomotive, transit, and off highway vehicle applications.
Vacuum Control
Vacuum contactors and starters were designed for starting and controlling three-phase, 50/60 Hz, AC motors.
Each contact is enclosed in a vacuum bottle to reduce and contain arcing. Excellent for plugging and jogging
applications.
DC Contactors
DC mill type and definite purpose contactors are designed for heavy industry service and are suitable for use
on moving machinery. Used in sever environmental and vibration conditions. Applications include mining, cranes
and transportation.
Manual Motor Control
Manual motor protectors (MMP) provide an economical solution for applications requiring manual starting and
stopping of motors. They can be used as Manual Motor Starters, Manual Motor Disconnects, IEC Circuit Breakers
(European market), NEC Group Installation Motor Starters, UL508 Type E Self-protected Manual Combination Starters
and UL508 Type F Combination Motor Controllers (when used in conjunction with a contactor).
Overload Relays and Heaters/Heater Packs
Available with NEMA or IEC ratings, overload relays are provided to protect motors, motor control apparatus,
and motor-branch circuit conductors against excessive heating due to motor overloads and failure to start modes.
Heaters/Heater Packs provide over-current protection to overload relays and finally to the starter. Interchangeable
heater packs are adjustable to match a motor's full load amperes and calibrated for use with 1.0 and 1.15 service
factor motors.
Automation Options
Eaton Electrical provides the best possible solutions for controlling and monitoring devices on the factory
floor. There are direct connections to the IT. Family of Starters for industrial fieldbus support and a line of
network adapters and I/O modules for remote I/O and panel applications.
Since all the Automation Hardware devices are communication enabled, each device is supported by CHStudio Component
Manager. This software tool enables the user to configure, monitor and diagnose device problems over any supported
industrial network.
Power Supplies
IT. series of low-voltage power supplies for motor control devices are the perfect solution for
powering control systems. In addition to 24VDC control, the IT. power supplies have a high outrush capacity, higher
input voltage range than the competition, long ride through capability and the choice of DIN rail or panel mount
units.

Enclosure Types
Enclosures provide mechanical and electrical protection for operator and equipment. Brief descriptions of the
various types of enclosures offered by Cutler-Hammer are given below. See NEMA Standards Publication No. 250 for
more comprehensive descriptions, definitions and/or test criteria.
NEMA Type 1 (Conforms to IP40) for Indoor Use
Suitable for most applications where unusual service conditions do not exist and where a measure of protection
from accidental contact with enclosed equipment is required. Designed to meet tests for rod entry and rust resistance.
Enclosure is sheet steel, treated to resist corrosion. Depending on the size, knockouts are provided on the top,
bottom and sometimes on the side.
NEMA Type 3R (Conforms to IP52) for Outdoor Use
Primarily intended for applications where falling rain, sleet or external ice formations are present. Gasketed
cover. Designed to meet tests for rain, rod entry, external icing and rust resistance. Enclosure is sheet steel,
treated to resist corrosion. Depending on the size, a blank cover plate is attached to the top (for a conduit hub)
and knockouts are provided on the bottom. Cover-mounted pilot device holes are provided and covered with hole plugs.
NEMA Type 4 (Conforms to IP65) for Indoor or Outdoor Use
Provides measure of protection from splashing water, hose-directed water and wind blown dust or rain. Constructed
of sheet steel with gasketed cover. Designed to meet tests for hose-down, external icing and corrosion protection.
Enclosure has two water- tight hubs (power) installed top and bottom of one control hub installed in bottom - depending
on size. Cover-mounted pilot device holes are provided and covered with hole-plugs.
NEMA Type 4X (Conforms to IP65) for Indoor or Outdoor Use
Provides measure of protection from splashing water, hose-directed water, wind blown dust, rain and corrosion.
Constructed of stainless steel with gasketed cover. Designed to meet the same tests as Type 4 except the enclosure
must pass a 200-hour salt spray corrosion resistance test.
NEMA Type 7 for Hazardous Gas Locations
For use in Class I, Group C or D indoor locations as defined in the National Electrical Code. NEMA Type 7 enclosures
must withstand the pressure generated by explosion of internally trapped gases and be able to contain the explosion
so that gases in the surrounding atmosphere are not ignited. Under normal operation, the surface temperature of
the enclosure must be below the point where it could ignite explosive gases present in the surrounding atmosphere.
Designed to meet explosion, temperature and hydrostatic design tests.
NEMA Type 9 for Hazardous Dust Locations
For use in Class II, Group E, F or G indoor locations as defined in the National Electrical Code. Heat generating
devices within the enclosure are designed to maintain the surface temperature of the enclosure below a point where
it could ignite the dust-air mixture in the surrounding atmosphere or cause discoloration of surface dust. These
enclosures are designed to meet tests for dust penetration, temperature and aging of gasket (if used).
NEMA Type 12 (Conforms to IP62) for Indoor Use
Provides a degree of protection from dripping liquids (non-corrosive), falling dirt and dust. Designed to meet
tests for drip, dust and rust resistance. Constructed of sheet steel. Hole plugs cover pilot device holes. There
are no knockouts, hub cover plates or hubs installed. Many Cutler-Hammer NEMA Type 12 enclosures are suitable for
use in Class II, Division 2, Group G and Class III, Divisions 1 and 2 locations as defined in the National Electrical
Code.
NEMA Type 12 Safety Interlock
The Type 12 enclosure can be ordered with a safety interlock on the door that can be
padlocked off. A vault-type door latch system is used. A tapered plate holds the gasketed door tight against the
case edge to provide a positive seal. The special door interlock consists of the door handle and a screwdriver
operated cover defeater. The cover defeater and the disconnect interlock defeater are both recessed screwdriver
operated devices which cannot be manipulated with other types of tools.
