30、SION FROM UL INTRODUCTION 1 Scope 1.1 The requirements in Part I of this Standard apply to enclosed capacitors with integral protection intended to reduce the risk of rupture and venting of the capacitor enclosure under internal fault conditions. These requirements apply to capacitors with expansion

31、 type protection rated 5 kilovolts or less, and capacitors with segmented lm type protection rated 2 kilovolts or less that are intended for use with appliances, lighting equipment, air conditioning and refrigeration equipment, motors, and the like, that comply with the requirements for such applian

32、ces and equipment. 1.1 revised July 26, 2012 1.1.1 The requirements of Part I may also be used to evaluate the construction only of these types of capacitors with ratings greater than the values noted in 1.1 but no greater than 7.2 kilovolts. Capacitors employing polymeric enclosures or capacitors e

33、mploying a partial metallic enclosure (i.e. remainder of enclosure such as the cap/cover which is not crimped to the case) that are not provided with internal protection and intended to be located in circuits not requiring fault current protection may be evaluated using only the construction require

34、ments of Part I. 1.1.1 revised July 26, 2012 1.2 The requirements in Part II of this standard apply to general-use power-factor-correction units consisting of one or more capacitors with or without protective fusing or overloads, with or without a switch or other disconnect device all within a prote

35、ctive enclosure; rated 600 volts maximum and intended for power-factor correction of circuits in accordance with the National Electrical Code, ANSI/NFPA 70. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, ANSI/NFPA 70, where the amb

36、ient temperature does not exceed 40C (104F) maximum. Exception: The requirements of Part II of this standard do not apply to power factor correction units containing automatic or other circuit monitoring/conditioning controls or automatic systems of multiple connected power factor correction units.

37、Power factor correction units with these additional features shall be evaluated to the Standard for Industrial Control Panels, UL 508A as an industrial control panel. Revised 1.2 effective May 21, 2012 1.2.1 A component capacitor used in a power factor correction unit as described in Part II of this

38、 Standard has been evaluated for across-the-line applications in accordance with Part I of this Standard and has been evaluated for a minimum fault current rating of 10K AFC. 1.2.1 revised March 3, 2008 1.2.2 The requirements of Supplement SA apply to electrolytic capacitors for motor start or simil

39、ar applications including dc circuits rated 600 V or less. 1.2.2 added March 3, 2008 1.3 A capacitor that complies with the requirements in Part I of this standard is intended to be mounted within an appliance or within equipment for which an acceptable outer enclosure is provided. 1.4 The requireme

40、nts in Part I and Part II do not apply to capacitors covered by the Standard for Across-the-Line, Antenna Coupling, and Line-by-Pass Capacitors for Radio- and Television-Type Appliances, UL 1414.

41、STRIBUTION WITHOUT PERMISSION FROM UL 1.5 Other types of capacitors may be investigated to establish compliance with these requirements, and with such additional test criteria as may be found necessary. 1.6 A product that contains features, characteristics, components, materials, or systems new or d

42、ifferent from those covered by the requirements in this standard, and that involves a risk of re or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of

43、 this standard. A product whose features, characteristics, components, materials, or systems conict with specic requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for developm

44、ent, revision, and implementation of this standard. 1.6 revised March 3, 2008 2 Glossary 2.1 For the purpose of this standard the following denitions apply. 2.2 CAPACITOR ROLL The layered and rolled interior windings of a capacitor, which is also known as the element. 2.2.0 CLASS 2 CIRCUIT A circuit

45、 supplied by a Class 2 source in accordance with Article 725 of the National Electrical Code (NEC). 2.2.0 added March 3, 2008 2.2.1 COMPONENT CAPACITOR Refers to a capacitor evaluated to Part I of the Standard. A component capacitor is also referred to as capacitor. 2.2.1 added August 24, 1998 2.3 C

46、ONTROLLED ENVIRONMENT An environment that is relatively free of conductive contaminants, such as carbon dust and the like, that may result from the end-use equipment in which a capacitor or power-factor correction unit is installed or due to the location of the end-use equipment, and that is provide

47、d with protection against humidity and the formation of condensation. 2.3.1 DRY TYPE CAPACITOR A capacitor that contains no liquid and utilizes a solid dielectric medium other than wax. 2.3.1 added March 3, 2008 2.3.2 ELECTRODE, FOIL TYPE Capacitor plates consisting of thin metal or “foil” separated

48、 by a dielectric. 2.3.2 added March 3, 2008 2.3.3 ELECTRODE, METALLIZED Capacitor plates consisting of dielectric material covered with metallic deposits such as aluminum on the surface. This type of electrode has a tendency to self restore or re-heal after local breakdown of the dielectric. 2.3.3 a

49、dded March 3, 2008 2.3.4 ELECTROLYTE Current conducting solution (liquid, gel, or solid) between two electrodes or plates of an electrolytic capacitor at least one of which is covered by a dielectric lm. 2.3.4 added March 3, 2008 MARCH 3, 2008 CAPACITORS - UL 810 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.3.5 ELECTROLYTIC CAPACITOR A capacitor consisting of two conducting electrodes whose anode has a metal oxide lm.
