Schneider Electric LC1D Series Contactor, 24 V ac Coil, 4-Pole, 25 A, 4NO, 690 V ac

The Schneider Electric LC1DT25B7 model is a 4 pole contactor featuring a 24 V ac operating coil, with an AC-3 full load current rating of 25 A.

Both the primary and secondary sections are supplied by an off-line flyback circuit based on VIPER267KDTR high voltage converter for ultra-wide input which provides regulated voltages to the control board, the gate driver ICs and the signal conditioning circuits.

Formal testing and measurement results confirm the ability and performance of ST power products combined with comprehensive digital control to deliver high efficiency, power factor near unity, and low THD across wide input voltage and load conditions.
