Product Description

Application

The NDC3-38 AC contactors are suitable for AC circuits with a frequency of 50Hz or 60Hz and a rated insulation voltage of 690V. Under AC-3 (Ue 380/415 V), it provides a rated operational current (Ie) of 38 A and a thermal current (Ith, AC-1, ≤60°C) of 50 A, supporting frequent motor starting and control. Its maximum controllable three-phase motor power (AC-3) reaches 9 kW at 220/240 V and 18.5 kW from 380/400 V up to 660/690 V.
