The highest priority for any electrical installation is to protect personnel from electrical shock hazard. Souriau-Sunbank by Eaton decided to have the UTL series qualified by UL per the UL 1977 standard and also according to the IEC 61984 standard. The connector is designed to be engaged or disengaged during normal use when live or under power load. First-mate, last-break contact mating is on the ground line, which is an important design feature of the UTL series. In addition, the connector is compliant with the latest environmental regulations such as RoHS and its Chinese equivalent.
