008100-000000-0000001 Scope
1.1 The requirements in Part II 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 type protection rated 5 kV or less, and capacitors with segmented film type protection rated 2 kV 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 appliances and equipment.
1.2 The requirements of Part II may also be used to evaluate the construction only of these types of capacitors with ratings greater than the values noted in 1 but no greater than 7.2 kV. Capacitors employing polymeric enclosures or capacitors employing 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 requirements of Part II.
1.3 The requirements in Part IIII 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 protective enclosure; rated 600 V maximum and intended for power-factor correction of circuits in accordance with the National Electrical Code, NFPA 70. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, NFPA 70, where the ambient temperature does not exceed 40°C (104°F) maximum. See 4.
1.4 The requirements of Part IIII 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. 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.
1.5 A component capacitor used in a power factor correction unit as described in Part IIII of this Standard has been evaluated for across-the-line applications in accordance with Part II of this Standard and has been evaluated for a minimum fault current rating of 10k AFC.
1.6 The requirements of Supplement SA apply to electrolytic capacitors for motor start or similar applications including dc circuits rated 600 V or less.
1.7 A capacitor that complies with the requirements in Part II of this standard is intended to be mounted within an appliance or within equipment for which an acceptable outer enclosure is provided.
1.8 The requirements in Part II and Part IIII do not apply to capacitors covered by the Standard for Fixed Capacitors for Use in Electronic Equipment – Part 14: Sectional Specification: Fixed Capacitors for Electromagnetic Interference Suppression and Connection to the Supply Mains, UL 60384-14.
1.9 Other types of capacitors may be investigated to establish compliance with these requirements, and with such additional test criteria as may be found necessary.
