Leviton® 333 mV Current Transformers (CTs) support the series 4000, series 4100, series 7000 and series 7100 lines of revenue-grade meters and help meet all measurement and verification based opportunities, including smart metering and LEED rating achievement. Designed as part of a simple and effective process for accurately capturing measurements of power consumption, CTs are easy to specify and install for new construction and retrofits. The better the equipment, the better the measurement. Leviton® meters utilize highly accurate current transformers for revenue-grade performance certified to ANSI standards. Solid core CTs are standard for high quality, long term accuracy and reliability. For added safety, all Leviton® current transformers come with built-in voltage suppression devices that prevent hazardous voltages from developing on CT secondaries should they become disconnected from a meter with load current present. Leviton® CTs are UL and cUL listed devices.
