Schneider Electric LC1D Series Contactor, 25A Operational Current, 110V Coil Voltage - LC1D128FD


This contactor is a four-pole switching device designed for industrial control of resistive loads using a DC control coil. It is intended for panel or rail installation in automation and electrical systems, offering a Compact footprint and protection for signalling circuits, while operating across a wide ambient temperature range.

Features & Benefits


• 25A rated operational current for dependable AC-1 switching
• 110V DC Coil with integral suppression for reduced Coil spikes
• 690V insulation for high-voltage resistive applications
• Screw clamp terminals enabling 1 to 4mm2 conductor connections
• 3600 cycles/hour maximum switching rate for frequent operations
• 53.55 to 72.45ms closing time for predictable response

Applications


• Suitable for resistive heating element switching in industrial processes
• Ideal for control panels requiring Compact 45mm width components
• used with signalling circuits where mechanically linked auxiliary contacts are needed
• Can be used for AC and DC power circuits up to 690V in machinery control

What Terminal types and conductor sizes does it accept?


Power and control terminals use screw clamps accommodating 1 to 4mm2 flexible or solid conductors and 1 to 2.5mm2 with ferrules on specified terminals.

How does it behave under high switching demand?


It supports up to 3600 cycles/hour at 60°C and has electrical endurance of 0.8M cycles at 25A AC-1.

What protection and safety characteristics are provided for the signalling circuit?


The signalling circuit includes a 1NO+1NC mechanically linked contact, minimum switching capability down to 17V and 5mA, and specified making/breaking currents per IEC standards.

How does ambient temperature affect control voltage limits?


Control voltage drop-out and operational limits vary with temperature

defined operating ranges adjust between -40 to 70°C and 60 to 70°C with specified Uc fractions.
