(Basic insulation class on 200 V working voltage)
Low power consumption (100-140 mW)
APPLICATIONS
Electronic switching systems, PBX, Terminal equipment, Telephone system
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.
