DATA S H E E T MINIATURE SIGNAL RELAY EA2 SERIES COMPACT AND LIGHTWEIGHT DESCRIPTION The EA2 series has reduced package size and power consumption to other NEC Conventional relays. Furthermore, it complies with 1500 V surge-voltage requirement of FCC part 68 by the unique structure and the efficient magnetic circuit FEATURES ™ Low power consumption ™ Compact and light weight ™ 2 form c contact arrangement ™ Low magnetic arrangement ™ Breakdown voltage : 1000 Vac (surge voltage 1500 V), FCC Part 68 compliant ™ Tube packaging ™ UL recognized (E73266), CAS certified (LR46266) APPLICATIONS Electronic switching systems, PBX, key telephone systems, automatic test equipment and other electronic equipment. ATTENTION DO NOT EXCEED MAXIMUM RATINGS. Do not use relays under exceeding conditions such as over ambient temperature, over voltage and over current. Incorrect use could result in abnormal heating, damage to related parts or cause burning. READ CAUTIONS IN THE SELECTION GUIDE. Read the cautions described in NEC's "Miniature Relays" (ER0046EJ∗) when you choose relays for your application.
