TeSys D contactor - 4P(4 NO) - AC-1 - <= 440 V 20 A - 24 V AC 50/60 Hz coil
LC1DT20B7
Description
TeSys D contactor, 4 poles (4NO), for non-inductive load applications up to 20A/440V AC-1. It provides a 24V 50/60Hz AC coil, 1NO+1NC built-in auxiliary contacts (NC mirror certified), connection by screw clamp terminals. For operating rates until 3600 cycles/hour and environments until 60°C, it procures high reliability and durability. Compact (45mm width), DIN-rail mounting or screw fixing. Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHS/REACh).
