Schneider Electric LC1DT25M7 TeSys D Contactor – 25A, 440V AC-1, 220V AC Coil
The Schneider Electric LC1DT25M7 is a TeSys D / TeSys Deca 4-pole contactor with 4 normally open (4NO) power contacts, rated 25A at up to 440V AC-1. It features a 220V AC 50/60Hz coil, integrated 1NO + 1NC auxiliary contacts, and screw-clamp terminals, making it suitable for resistive loads, HVAC systems, industrial control panels, and electrical switching applications.
Description
The Schneider Electric LC1DT25M7 TeSys D contactor is designed for reliable switching and control of resistive electrical loads in industrial, commercial, and HVAC installations. Its 4-pole (4NO) configuration provides four normally open power contacts, with a rated operational current of 25A at ≤440V AC under AC-1 utilization.
The contactor operates with a 220V AC control coil at 50/60Hz and incorporates 1NO + 1NC auxiliary contacts, providing additional control and signalling functionality. The LC1DT25M7 uses screw-clamp terminals and can be installed on a 35mm DIN rail or by screw fixing, while its compact 45mm width helps optimize control-panel space.
With a maximum operating rate of 3,600 cycles per hour at 60°C, 15 million mechanical operating cycles, and an operating ambient range extending to 60°C, the TeSys D contactor is designed for demanding switching applications.
The LC1DT25M7 Schneider contactor is suitable for HVAC control panels, industrial automation, heating and ventilation systems, resistive loads, lighting control, electrical distribution panels, and general-purpose AC switching applications.
