适用范围
These requirements cover single and multipole connectors@ intended for factory assembly to copper or copper alloy conductors or printed wiring boards@ for use in data@ signal@ control and power applications within and between electrical equipment. These requirements apply to devices categorized as follows (See Figure 1.1): a) Type 0 rated less than 8.3 A and less than 30 V rms (42 V peak); b) Type 1A rated less than 8.3 A and from 30 V up to and including 600 V ac or dc@ or both; c) Type 1B rated from 8.3 A up to and including 200 A@ and less than 30 V rms (42 V peak); d) Type 2 rated from 8.3 A to less than 31 A and from 30 V up to and including 600 V ac or dc or both; e) Type 3 rated from 31 A up to and including 200 A and from 30 V up to and including 600 V ac or dc@ or both. f) Type 4 rated from greater than 200 A up to and including 1000 A@ and up to and including 600 V ac or dc. g) Type 5 rated less than 31 A and from 601 V up to and including 6000 V ac or dc@ or both. Type designations used in this Standard only serve as a guide to determine appropriate requirements@ and do not represent an assigned rating. A device without an assigned current rating is considered to be either a Type 0 or Type 1A depending upon the assigned voltage rating. This standard does not directly apply to the following devices@ but may be used to supplement the requirements within these standards when a device is evaluated to these standards: a) Devices produced integrally with flexible cord or cable that are covered by the Standard for Cord Sets and Power-Supply Cords@ UL 817; b) Devices intended for connection to the branch circuit@ such as attachment plugs@ cord connectors@ receptacles@ inlets@ and outlets@ that are covered by the Standard for Attachment Plugs and Receptacles@ UL 498; c) Devices solely intended for direct connection to the branch circuit in accordance with the National Electrical Code@ NFPA 70@ and that are provided with contacts of the pin and sleeve type@ that are covered by the Standard for Plugs@ Receptacles@ and Cable Connectors of the Pin and Sleeve Type@ UL 1682; d) Devices consisting of wiring terminals and supporting blocks intended for the connection of wiring that are covered by the Standard for Terminal Blocks@ UL 1059; e) Devices intended for use with telecommunications networks@ that are covered by the Standard for Information Technology Equipment ?C Safety ?C Part 1: General Requirements@ UL 60950-1@ or the Standard for Communications Circuit Accessories@ UL 1863; f) Devices such as wire connectors and soldering lugs that are covered by the Standards for Wire Connectors@ UL 486A-486B; Splicing Wire Connectors@ UL 486C; or Equipment Wiring Terminals for Use with Aluminum and/or Copper Conductors@ UL 486E; g) Devices such as quick-connect terminals that are covered by the Standard for Electrical Quick-Connect Terminals@ UL 310. The requirements in this standard may not entirely address all possible situations due to the wide variety of products and designs. In those situations@ the Standard for Attachment Plugs and Receptacles@ UL 498 may be used to supplement the requirements in this standard. Where a conflict exists between the requirements of UL 498 and UL 1977@ the requirements of UL 1977 shall take precedence.
