NEMA contact ratings : ウィキペディア英語版 | NEMA contact ratings NEMA contact ratings are how much current at a rated voltage a relay or other pilot device can switch. The current rating of smaller NEMA contactors or their auxiliaries are defined by ''NEMA ICS 5: Industrial Control and Systems, Control Circuit and Pilot Devices''〔(【引用サイトリンク】url=http://www.nema.org/stds/ics5.cfm )〕 standard. The nomenclature is a letter followed by a three digit number, the letter designates the current rating of the contacts and the current type (i.e., AC or DC) and the number designates the maximum voltage design values. == AC Contact Ratings ==
