Schneider Electric LC1F185M7 TeSys F 185 A Contactor 220 V AC

LC1F185M7 large-frame 185 A contactor for heavy motors

The LC1F185M7 is a Schneider Electric product listed in the datasheet as: Contactor, TeSys F, 3P(3NO), AC-3 <=440V 185A, 220V AC coil. The LC1F185M7 is a large three-pole TeSys F contactor rated at 185 A in AC-3 up to 440 V. The F range covers the heavy end of motor starting, where the contactor is bolted to a plate and cables are connected with lugs. Seven Star LLC supplies the LC1F185M7 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: LC1F is the TeSys F range, 185 is the AC-3 current in amps at up to 440 V, and M7 is the coil code for 220 V AC. Check the datasheet lifecycle notice, because this reference is shown as discontinued, which makes it a replacement part for existing panels.

Technical specifications of the LC1F185M7

Power and coil data of the LC1F185M7

Rated motor power: 90 kW at 380 to 400 V AC 50/60 Hz (AC-3); 100 kW at 415 V AC 50/60 Hz (AC-3); 100 kW at 440 V AC 50/60 Hz (AC-3). Rated operational voltage: <= 460 V DC; <= 690 V AC 50/60 Hz. Rated operational current: 275 A (at <40 °C) at <= 440 V AC-1; 185 A (at <55 °C) at <= 440 V AC-3. Utilisation categories: AC-3; AC-4; AC-1. Motor power ratings: 90 kW at 380 to 400 V AC 50/60 Hz (AC-3); 100 kW at 415 V AC 50/60 Hz (AC-3); 100 kW at 440 V AC 50/60 Hz (AC-3). Coil or control voltage: 220 V AC 40 to 400 Hz. Mechanical durability: 10 Mcycles.

The coil of a large contactor draws a high inrush when it closes, so the control transformer and wiring must be sized for that peak, not for the hold-in value. The datasheet lists coil consumption values you should compare with the control circuit.

Replacement and successor planning for the LC1F185M7

Because the datasheet carries a discontinued notice, treat this part as a spare or replacement and confirm with the supplier the successor reference, coil code, terminal shrouds and accessories before ordering. Auxiliary contact blocks, mechanical interlocks and coil suppressors from the same family should be checked for fit.

When a panel contains several LC1F units, standardise the coil voltage and keep a complete spare with the same coil code.

The datasheet downloaded for this page carries lifecycle notices: Discontinued on: Jun 15, 2023. For a plant that already runs this reference that makes the LC1F185M7 a spare-and-replacement item, and it is worth fixing the stock level and the long-term successor plan at the same time. We can discuss compatible alternatives once we know the installation.

Selection checklist for the LC1F185M7

• Motor current and duty class (AC-3 185 A at up to 440 V).
• Coil voltage: 220 V AC for this reference; check the control supply.
• Lifecycle status and a successor plan.
• Thermal overload relay or electronic relay range for the motor.
• Cable lugs and busbar connection method.
• Accessories: auxiliary blocks, suppressors, interlock kit.

Handling, fitting and testing of the LC1F185M7

A contactor in this class is heavy; use two people or lifting aids when fitting it in a tall panel. Fix it with the specified screws on a rigid plate, use cable lugs of the correct size and apply the torque of the datasheet.

After fitting, check manual operation of the armature, measure coil resistance and perform a dry run before connecting the motor load.

Typical applications of the LC1F185M7 in Oman and the GCC

In Oman and the GCC large contactors of this class are found on crude and water transfer pumps, compressors, large fans and crushers, often in older MCC panels that are still in service and need like-for-like replacement.
