Specifications Parameter Specification Product Range TeSys D (LC1D Series) Device Type Electromechanical Contactor Model LC1D25 Coil Voltage / Type 24 Volts DC (24V DC) Rated Operational Current (Ie) @ AC-3 25 A at 380-440V AC. This is its motor switching capacity for squirrel-cage motors. Rated Operational Power (P) @ AC-3 11 kW (15 HP) at 400V AC. Thermal Current (Ith) 25 A Utilization Categories (IEC/EN 60947-4-1) AC-1: Non-inductive or slightly inductive loads — 55A. AC-3: Squirrel-cage motors (starting, switching off during running) — 25A. AC-2: Slip-ring motors — 25A. AC-4: Squirrel-cage motors (plugging, inching) — 17.5A. Rated Insulation Voltage (Ui) 690V AC Rated Operational Voltage (Ue) Up to 690V AC / 440V DC (for specific categories). Number & Type of Main Poles 3 Normally Open (3NO) power contacts (for 3-phase). Some variants offer 4 poles (3NO + 1NO) or 1NO+1NC. Control Coil Power Consumption Pull-in (Start): ~25 W (for DC coils, this translates to an inrush current). Holding (Sealed): ~3.5 W (very low holding power). Mechanical Life 10 to 30 million operations (depending on conditions). Electrical Life AC-3: 1.5 to 3 million operations at rated current. Mounting Snap-on mounting to 35mm symmetrical DIN rail (EN 60715) or screw mounting. Terminals Screw clamp terminals suitable for both rigid and flexible copper conductors. Ambient Temperature -25°C to +60°C (operation), -40°C to +85°C (storage). Standards Compliance IEC/EN 60947-4-1, UL 508, CSA C22.2 No. 14. Typical Coil Resistance Approximately 200 Ohms (for 24V DC coil). This can be used to verify coil health with a multimeter. Weight ~ 0.33 kg.
