The document describes current transformers designed for compact circuit-breakers. These transformers are available in three-phase designs and are molded in polyurethane for space efficiency and easy installation. They are approved for official calibration.
Mg t3
Available ratings: 100/5 A, 150/5 A, 200/5 A, 250/5 A, 300/5 A with a performance class of 0.5 or 0.5S.
Each unit contains three current transformers, one per phase.
Primary busbars are nickel-plated copper, and secondary terminals support up to 6 mm2.
Mg t5
Available ratings: 200/5 A, 250/5 A, 300/5 A, 400/5 A, 600/5 A with a performance class of 0.5S.
Each unit contains three current transformers, one per phase.
Primary busbars are nickel-plated copper, and secondary terminals support up to 6 mm2.
The voltage signals of the four primary conductors are accessible at the terminal block, facilitating easy connection and monitoring.
