Schneider Electric LC1DT25MD TeSys D Contactor – 25A, 440V AC-1, 220V DC Coil

Description

The Schneider Electric LC1DT25MD TeSys D Contactor is a compact and reliable 4-pole contactor from the TeSys D / TeSys Deca range, designed for switching resistive and non-inductive loads in industrial and commercial electrical systems.

The LC1DT25MD features 4 normally open (4NO) main contacts and is rated at 25A under AC-1 utilization at up to 440V AC. This makes it particularly suitable for resistive loads, heating applications, HVAC equipment, lighting systems, and general electrical switching, rather than being primarily selected for motor AC-3 duty.

The contactor is equipped with a 220V DC standard control coil, making it suitable for control systems that use a 220V DC control supply. This is especially useful in industrial automation, control panels, substations, and applications where DC control circuits are preferred.

The LC1DT25MD also incorporates 1 NO + 1 NC auxiliary contacts, providing additional contacts for control logic, electrical interlocking, feedback, signaling, and status indication.

The power circuit supports an operational voltage of up to 690V AC, while the contactor is rated at 25A AC-1 at 440V AC. This provides flexibility for a broad range of low-voltage switching applications.

For installation, the Schneider LC1DT25MD uses screw-clamp terminals and can be mounted using 35mm DIN rail or screw fixing, making it convenient for electrical cabinets and automation panels.

With the proven TeSys D platform, international certifications, and compact construction, the LC1DT25MD is a practical solution for industrial automation, heating control, HVAC systems, resistive loads, and electrical control panels requiring a 220V DC coil.
