UL 60730-2-4-2003 UL Standard for Safety Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Thermal Motor Protectors for Motor-Compressors of Hermetic and Semi-Hermetic Type First Edition
1 Scope and normative references
This clause of Part 1 is replaced by the following
1 1 This standard applies to the partial evaluation of THERMAL MOTOR PROTECTORS as defined in lEC
Publication 60730-1 for sealed(hermetic and semi-hermetic type)motor-compressors
A THERMAL MOTOR PROTECTOR is an INTEGRATED CONTROL which is dependent On its correct mounting and fixing in or on a motor and which
can only be fuIly tested in combination with the relevant motor
Requirements concerning the testing of the combination of motor and THERMAL MOTOR PROTECTOR are given in IEC Publication
60335—2—34
This standard applies to THERMAL MOTOR PROTECTORS for motor compressors using NTC or PTC THERMISTORS
additional requirements for which are contained in Annex J
1．1DV DE Addition ofthe following Note to f．f ofthe part2
NOTE--Requirements concerning the testing of the combination of hermetic motor-compressor and
THERMAL MOTOR PROTECTOR are given in UL 60335-2-34．
1 1 1 This standard applies to the inherent safety，to the OPERATING VALUES，OPERATING TIMES，and OPERATING
SEQUENCES where such are associated with equipment safety and to the testing of THERMAL MOTOR PROTECTORS
used in or on sealed(hermetic and semi—hermetic type)motor—compressors
This standard applies to THERMAL MOTOR PROTECTORS for motor-compressors within the scope of IEC
Publication 60335
Throughout this standard the word％quipment'’means"appliance and equipment'’
THERMAL MOTOR PROTECTORS for motor compressors not intended for normal household use，but which
nevertheless may be used by the public，such as equipment intended to be used by laymen in shops，in
light industry and on farms，are within the scope of this standard
This standard does not apply to THERMAL MOTOR PROTECTORS designed exclusively for industrial applications
1．1．1DV D2 Modification of 7．1．1 ofthe part2
This standard applies to THERMAL MOTOR PROTECTORS for motor-compressors within the scope
Of UL 60335-2-34．
1 1 2 This standard does not apply to other means of motor protection
