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. Type designations used in this Standard only serve as a guide to determine appropriate requirements, and do not represent an assigned rating. A device not assigned a current rating is considered either to be Type 0 or Type 1A depending upon the assigned voltage rating. This standard does not directly apply to the following but may supplement other applicable 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, covered by the requirements 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 Telephone Equipment, UL 1459, 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 - For Use With Copper Conductors, UL 486A; Splicing Wire Connectors, UL 486C; or Equipment Wiring Terminals, UL 486E; g) Devices such as quick-connect terminals that are covered by the Standard for Quick Connect Terminals, UL 310.
