DATA S H E E T MINIATURE SIGNAL RELAY EC2 SERIES COMPACT AND LIGHTWEIGHT, SMALL MOUNTING SIZE, HIGH BREAKDOWN VOLTAGE DESCRIPTION The EC2 series has reduced mounting space but sustained high-performance of NEC EA2 series. Furthermore, it complies with 2500 V surge-voltage requirement of Bellcore specification. FEATURES ™ Compact and light weight ™ 2 form c contact arrangement ™ Low power consumption ™ Reduced mounting space : 15 mm × 7.5 mm ™ High-breakdown voltage of coil to contacts : 1500 Vac, 2500 V (rise time : 2 µs, fall time : 10 µs) ™ Capable of High-power switching : 700 Vac, 4.2 A, 4 times in case of accident ™ UL recognized (E73266), CAS certified (LR46266) APPLICATIONS Electronic switching systems, PBX, terminal equipment, telephone systems. For Right Use of Miniature Relays 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.
