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 TM Low power consumption TM Compact and light weight TM 2 form c contact arrangement TM Low magnetic arrangement TM Breakdown voltage : 1000 Vac (surge voltage 1500 V), FCC Part 68 compliant TM Tube packaging TM 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.
