The JM21F series of split-core current transformer offers a 100mA output and has mounting options for panel mounting 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 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.
The ‘F’ denotes that this model has a ferrite core.
• Core contact surface is waterproofed, however if it gets
rusty, use WD-40 or CRC5-56 to remove the rust for accurate performance
• Lead wires available in custom lengths
