The GTZ4121 current transformer acquires heating current and is used in combination with a controller for heat current monitoring. It is capable of transforming up to 4 alternating currents into 4 different direct voltages. The three line currents in 3-phase systems are transformed into a summated voltage when appropriately wired.

Current transformer for top-hat rail mounting for the acquisition of heating current with 4 inputs (1 3-phase current consumer + 1 AC current consumer or 4 AC current consumers)
