The JM21F series of split-core current transformer offers input of 5A-250A with 333mV output and mounting options for panel or DIN rails. The JM21F series is designed to be directly connected to a meter to eliminate the need for internal CTs yet provide accurate readings. This allows the same meter to be used to sense sources with various currents traveling through them. The JM21F-xxx-333mV includes an over-voltage protection circuit which provides an added level of safety to the unit. The JM21F is Class 0.5s or Class 1, depending on the burden.
