1.6 revised effective April 13, 2017<\/font><\/p>\n

1.7 These requirements cover equipment rated 1000 V or less nominal, 1058 V maximum ac and 1500 V maximum dc.<\/font><\/p>\n

1.8 This Standard does not apply to molded-case circuit breakers.<\/font><\/p>\n


1.8 revised effective April 13, 2017<\/font><\/p>\n

1.9 These circuit breakers are intended for installation in circuit breaker enclosures, switchboards (switchgear), panelboards, and the like. Drawout-mounted devices are intended for use with specific adapters or receiving equipment. The acceptability of the combination of a circuit breaker with respect to any overall enclosure will be determined when the complete product is considered.<\/font><\/p>\n
