Product details

It combines a contactor and fuse disconnector in one unit; the thermal overload relay is ordered separately. Rated for AC-3 utilisation category (IEC 60947-4-1), it switches motor loads in the standard duty cycle: starting, stopping, and running a squirrel-cage induction motor. The conventional free air thermal current is 18 A, and the control circuit runs on 110 V AC 50/60 Hz. Motor power capability depends on supply voltage: 7.5 kW at 380/400 V AC, 9 kW at 415 V or 440 V AC, 10 kW at 500 V AC, and 4 kW at 220/230 V AC.

The 18 A thermal current is the continuous current the starter can carry in free air — not the motor full-load current, but the rating the overload relay and contactor are sized around. The associated fuse rating is 20 A (10 x 38 mm aM type), which coordinates with the starter for short-circuit protection. The enclosure measures 330 mm high, 186 mm wide, and 175.5 mm deep — sized for a standalone wall-mount or machine-mount installation. Cable entries are provided top and bottom for ISO20, ISO25, ISO32, and ISO40 glands, giving flexibility for different cable diameters.

If you need a functional equivalent, the closest match would be a current-production TeSys LE or TeSys island DOL starter with the same 18 A thermal rating and 110 V AC coil — but the enclosure dimensions, cable entry layout, and mounting footprint may differ. Verify the physical fit before committing the BOM line. Condition is everything in this channel — specify whether you need new-in-box, pulled, or tested-used, and whether the original packaging matters for your quality documentation.

Frequently asked questions

What are the key ratings for the LE4D18F7?

18 A conventional free air thermal current (Ith), 110 V AC 50/60 Hz control voltage, AC-3 utilisation category per IEC 60947-4-1. Motor power ranges from 4 kW at 220/230 V AC up to 10 kW at 500 V AC. The enclosure is IP65 and IK07 rated.

What replaces the LE4D18F7?

No official successor order code is listed. A current-production TeSys LE or TeSys island DOL starter with 18 A rating and 110 V AC coil would be the functional equivalent, but enclosure dimensions and cable entry layout may differ — verify fit before substituting.

How do I source the LE4D18F7?

Since it is obsolete, sourcing is through surplus inventory or independent brokers. Submit an RFQ specifying condition requirements (new-in-box, pulled, tested) and packaging needs.
