Product details

The TeSys LC4D50F7 is a direct-on-line (DOL) starter combining a contactor and a fuse disconnector in one plate-mounted unit, rated for 50 A in AC-3 utilisation category — the standard duty for squirrel-cage motor switching. Motor power coverage spans 15 kW at 220…230 V up to 33 kW at 660…690 V, making it a single-starter solution across common European and North American line voltages.

The LC4D50F7 mounts to a plate, not a DIN rail. Its footprint is 281 mm wide by 143 mm high by 130 mm deep, so plan for a backplate with clearance for the fuse-disconnector handle swing and cable bending radius.

Frequently asked questions

Can I use LC4D50F7 for a 50 A motor?

Yes — the LC4D50F7 is rated 50 A in AC-3 duty, which is the standard category for starting and stopping squirrel-cage motors. It will switch a motor drawing up to 50 A under normal starting conditions.

Does LC4D50F7 have an overload relay?

No. The LC4D50F7 is a DOL starter that combines a contactor and a fuse disconnector. It does not include an overload relay; a separate thermal or electronic overload must be added in the motor circuit.

Does LC4D50F7 work with 3 phase motors?

Yes — the AC-3 utilisation category and the motor power ratings (15…33 kW across 220…690 V AC) are all three-phase induction motor values.
