Introduction
An enclosure is a surrounding case constructed to provide a degree of
protection to personnel against accidental contact with the enclosed
equipment and to provide a degree of protection to the enclosed
equipment against specied environmental conditions.
A brief description of the more common types of enclosures used by
the electrical industry relating to their environmental capabilities follows.
Denitions pertaining to nonhazardous locations
Type 1
Enclosures are intended for indoor use
primarily to provide a degree of protection
against limited amounts of falling dirt.
(NEMA Standard 7-15-1991.)
Type 4X
Enclosures are intended for indoor or outdoor
use primarily to provide a degree of protection
against corrosion, windblown dust and
rain, splashing water, hose-directed water
and damage from external ice formation.
(NEMA Standard 1-10-1979)
Refer to NEMA Standards Publication for more information regarding
applications, features and design tests.
Individual NEMA product Standards Publications or third party
certication standards may contain additional requirements for
product testing and performance.
Type 7
Enclosures are intended for indoor use in
locations classied as Class I, Groups, A, B,
C, or D, as dened in the National Electrical
Code. (NEMA Standard 7-15-1991.)
3
Type 3R
Enclosures are intended for outdoor use
primarily to provide a degree of protection
against rain, sleet and damage from external
ice formation. (NEMA Standard 7-15-1991.)
Type 4
Enclosures are intended for indoor or
outdoor use primarily to provide a degree
of protection against windblown dust and
rain, splashing water, hose-directed water
and damage from external ice formation.
(NEMA Standard 1-10-1979.)
Type 12
Enclosures are intended for indoor
use primarily to provide a degree of
protection against circulating dust, falling
dirt, and dripping noncorrosive liquids.
(NEMA Standard 7-15-1991.)
Type 13
Enclosures are intended for indoor
use primarily to provide a degree of
protection against dust, spraying of
water, oil and noncorrosive coolant.
(NEMA Standard 1-10-1979.)
Type 9
Enclosures are intended for indoor use in
locations classied as Class II, Groups E, F, or
G, as dened in the National Electrical Code.
(NEMA Standard 7-15-1991.)

Motors that have separate windings for each speed provide more combinations of
speed variations. Multi-speed starters from ABB Control are available for constant
horsepower, constant torque and variable torque motors.
Constant horsepower
Motors that maintain the same horsepower regardless of speed are called
constant horsepower motors. These motors are used in applications like
metal working.
Constant torque
Motors that maintain constant torque at all speeds are called constant torque
motors. In applications like conveyors, horsepower varies directly with speed.
Variable torque motors
Motors that produce a torque characteristic which varies as the square of
the speed are called variable torque motors and are used in applications like
blowers and fans.
