Schneider Electric LC1D Series Contactor, 40A Contact Current, 48V Coil Voltage - LC1DT40E7


This contactor is a compact, four-pole switching device designed for industrial motor control and resistive load switching in automation and electrical systems. It operates from a 48V AC control supply and is built to handle power circuits up to 690V, offering suitable switching capability for heavy-duty electrical installations while fitting plate or rail mounting arrangements.

Features & Benefits


• 40A rated operational current delivering continuous power handling
• 48V AC Coil providing standard industrial control voltage compatibility
• 4NO main contacts enabling four-pole simultaneous switching
• 1NO+1NC auxiliary contacts for local signalling and interlocks
• Screw clamp terminals allowing secure conductor connections
• 3600 cycles/hour maximum switching rate for high-frequency use

Applications


• Suitable for motor starters and contactor-based control panels
• Ideal for resistive load switching in industrial process lines
• used with PLC-driven control cabinets requiring auxiliary feedback
• Can be used for power distribution switching up to 690V systems

What are the expected electrical endurance figures for this device?


The device provides electrical durability to 1.4M cycles under a 40A AC-1 load at voltages up to 440V.

How does the contactor perform under short-time fault conditions?


It withstands short-time currents such as 240A for 10s and 380A for 1s on the power circuit at 40°C, and rated breaking capacity reaches 450A at 440V.

What control-coil inrush and holding power should be planned for?


Design for an inrush of around 70VA and a hold consumption near 7 to 7.5VA depending on supply frequency and cosφ.

How adaptable are the Terminal connections for different conductor types?


Terminals accept flexible and solid conductors with and without end ferrules across ranges up to 16mm² depending on conductor type and position.

Are there environmental limits to consider during installation?


Operate the device within ambient temperatures of -40 to 60°C and derate operation above 60°C

it is intended for use up to 3000m altitude.
