18、R DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 This standard covers solid-state overcurrent protectors. These devices are solid-state switches that limit the output current to a safe level when the output load exceeds the current-limit threshold or when a load-side short-circuit

19、is present. Solid-state overcurrent protectors are intended to be used on the load-side of an isolating transformer, power supply or battery to provide a means of supplementary protection. See Table 1.1 for maximum current and power levels. Table 1.1 Maximum current and power levels Output voltage (

20、V oc ) Output current (I sc ) V ac V dc A( V A) 20 20 1000 / V oc 250 20 V oc 30 20 V oc 30 1000 / V oc 250 3 0 V oc 60 1000 / V oc 250 1.2 The devices covered by these requirements are integrated circuits, and electrical spacings within the devices are not specied. 1.3 The devices covered by these

21、requirements are entirely electronic in nature and have no means for manual operation or reset. 1.4 The terminals of the devices covered by these requirements are for factory wiring only (intended to be mounted on a printed wiring board). 1.5 The devices covered by these requirements shall only be u

22、sed on supply circuits originating from an isolating transformer, a power supply or a battery with limited maximum current and power levels as noted in Table 1.1. Use on supply circuits with a higher power capability requires additional evaluation for reliability, such as those requirements containe

23、d in the Standard for Safety-Related Controls Employing Solid-State Controls, UL 991. 1.6 The devices covered by these requirements limit output currents to values less than the overcurrent protection rating of 5 amperes. 1.7 The devices covered by these requirements have only been evaluated for sup

24、plementary overcurrent protection of secondary circuits supplied by the load side of a transformer, power supply or battery and have not been evaluated for branch-circuit protection. 1.8 This standard may cover devices intended for use in telecommunications applications. However, devices intended fo

25、r connection to telecommunications networks with outside plant connections should be evaluated in the end-use in accordance with the requirements of the Standard for Information Technology Equipment Safety - Part 1: General Requirements, UL 60950-1, or the Standard for Secondary Protectors for Commu

27、: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.2 A component shall be used in accordance with its rating established for the intended conditions of use. 2.3 S

28、pecic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 3 Units of Measurem

29、ent 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 4 Undated References 4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition

30、 of that code or standard. 5 Glossary 5.1 For the purpose of this outline, the following denitions apply: 5.2 ENCAPSULANT A molding material that is typically cast or injection molded around and is intended to insulate and protect the device. Encapsulated devices do not employ supplementary surround

31、ing shells hence the encapsulant functions as an electrical enclosure. 5.3 EXPOSED PLANT (OUTSIDE PLANT) Any portion of the telecommunications network subject to accidental contact with or induction from power conductors at a voltage exceeding 300V to ground. This includes circuitry that is intended

32、 to be connected to the Public Switched Telephone Network (PST-N), Off-Premises Extension (OPE) lines, and the like. 5.4 MAXIMUM CONTINUOUS CURRENT (CONT. CURRENT) This designation is the ampere rating for which a protector or family of protectors has been tested for continuous current operation. 5.

33、5 PROTECTIVE CURRENT (PROT. CURRENT) This designation is the ampere rating for which a protector or family of protectors has been tested for providing overcurrent protection. 5.6 TELECOMMUNICATION (TELEPHONE) NETWORK CIRCUIT An electrical circuit conductively connected to the telephone company commu

34、nications facilities. 5.7 TELECOMMUNICATION NETWORK CONNECTIONS (TNC) Identied as follows: a) Not intended for use on telecommunication network with outside plant connections. b) Intended for use on telecommunication network with outside plant connections.

There shall be no emission of ame or molten metal

42、from the device during testing or evidence of a risk of re as determined by the indicator described in 10.2. 10.2 During the test, the grounding means is to be connected to ground through a 3-ampere non-time-delay fuse and the unit is to be draped with a double layer of cheesecloth conforming to the

43、 outline of the unit. 10.3 The component or circuit is to be mounted in its intended manner. 10.4 When a range of values for one component or circuit construction is to be evaluated, samples of the minimum, mean, and maximum rating are to be tested. All tests are to be conducted at a 25.0 3C ambient

44、. 10.5 The operating time and limiting shall be consistent and in accordance with the tolerances specied by the manufacturers curve of opening time versus current or wattage. 10.6 The manufacturers operating time curve is to be veried by checking four points, including high and low values, along the

45、 curve. Five separate component or circuit samples are to be used to check each of the four points. If no curve exists, this test shall be used to determine a set of reference points the component or circuit can be judged against after each of the required tests. 10.7 After each of the tests specied

46、 in Sections 12 18, the Calibrations Tests are to be repeated. The results are considered acceptable if there is no change in the measured operating characteristics of more than 5 percent.
