9、WITHOUT PERMISSION FROM ULPrefaceThis document provides a single listing of the technical National Differences included in the UL adoptionof the corresponding IEC standard.In its IEC-based standards, UL uses the notations indicated below to identify national difference type, andthese types are addit
10、ionally noted in this document. The standard may not use all types of thesedeviations.D1 - These are deviations which are based on basic safety principles and requirements, elimination ofwhich would compromise safety for U.S. consumers and users of products.D2 - These are deviations based on safety
11、practices. These are deviations for IEC requirements that maybe acceptable, but adopting the IEC requirements would require considerable retesting or redesign on themanufacturers part.DC - These are deviations based on the component standards and will not be deleted until a particularcomponent stand
12、ard is harmonized with the IEC component standard.DE - These are deviations based on editorial comments or corrections.DR - These are deviations based on the national regulatory requirements.Each national difference contains a description of what the national difference entails. Typically one of the
13、following words is used to explain how the text of the national difference is to be applied to the base IECtext:Addition / Add - An addition entails adding a complete new numbered clause, subclause, table,figure, or annex. Addition is not meant to include adding select words to the base IEC text.Del
14、etion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause,table, figure, or annex without any replacement text.Modification / Modify - A modification is an altering of the existing base IEC text such as theaddition, replacement or deletion of certain words or the
15、replacement of an entire clause,subclause, table, figure, or annex of the base IEC text.MAY 16, 2014 NATIONAL DIFFERENCES FOR UL UL 60730-2-10 3UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULNational Differences1.1DV D2 Addition of the follow
16、ing text to 1.1:This standard also covers centrifugal switches intended to be integrated into motors. Suchdevices are tested with the intended motor as an integrated control.1.1.3DV D2 Deletion of the following text from the second sentence of 1.1.3:or mechanically operated motor-starting devices1.2
17、DV D2 Addition of the following text to 1.2:The maximum voltage is 600 V. The maximum current is unlimited.2.2.101ADV D2 Addition of the following definition:2.2.101ADV.1 MOTOR STARTING CENTRIFUGAL SWITCHES: ELECTRICALLY OPERATED CONTROL intended forintegration in a motor and operates as a function
18、of the rotational speed of the motorshaft using the centrifugal force created from the rotating shaft.2.3DV D2 Addition of the following definitions:2.3DV.101 PICK-UP VALUE: PICK-UP VALUE denotes the declared value of voltage or current atwhich an electro-magnetic starting relay operates on a rise i
19、n voltage or current.Note This is also referred to as the make value.2.3DV.102 DROP-OUT VALUE: DROP-OUT VALUE denotes the declared value of voltage or currentat which an electro-magnetic starting relay operates on a fall in voltage or current.Note This is also referred to as the break value.2.3DV.10
20、3 CONTACT CHANGE VALUE: CONTACT CHANGE VALUE denotes the declared value of voltageor current at which an electro-thermal starting relay operates on a rise in voltage orcurrent.2.3DV.104 CONTACT HOLD VALUE: CONTACT HOLD VALUE denotes the declared value of voltage orcurrent at which an electro-thermal
21、 starting relay operates on a fall in voltage or current.6.3.101.4DV D2 Addition of the following text:MOTOR STARTING CENTRIFUGAL SWITCHESTable 7.2DV D2 Modification of Table 7.2 with the following seven national differences:DV.1 Insert row 101A, with the first column being “101A”, the second column

24、.DV.4 Insert row 104A, with the first column being “104A”, the second column being“Contact hold value”, the third column being “2.3DV.104, 17”, and the fourth column being“X”.DV.5 Revise row 101, with the first column being “105A”, the second column being“Steady state motor run current”, the third c
25、olumn being “14.4”, and the fourth columnbeing “X”.DV.6 Insert row 106A, with the first column being “106A”, the second column being “Datecode of manufacturing106A”, the third column being “blank”, and the fourth column being“C”.DV.7 Add: “Note 106A The date code shall be the date or other dating pe
26、riod ofmanufacture not exceeding any three consecutive months. The date of manufacture maybe abbreviated; or may be in a nationally accepted conventional code or in a code affirmedby the manufacturer, provided that the code:a) Does not repeat in less than 20 years, andb) Does not require reference t
27、o the product records of the manufacturer todetermine when the product was manufactured.”14.4DV D2 Modification of the above requirement by replacing it with the following:The heating test of clause 14 is applicable for Current Sensing and PTC Motor Startingdevices. For current sensing motor startin
28、g devices, the coil of the motor starter shall beloaded to the steady state motor run current declared in Requirement 105A of Table 7.2, atthe declared maximum operating voltage.For a PTC Motor Starting device, the loading shall be the same as a current motor startingdevice except that the PTC shall
29、 be in its tripped state.The contacts shall not be loaded. For Voltage Sensing and Centrifugal motor startingdevices, the heating test of clause 14 is not required since an insignificant heating of coilsor other parts are expected due to the inherent intermittent operation of these devices.17.16DV D
