It switches three-phase induction motors up to 33 kW at 660...690 V AC, 30 kW at 440 V, 25 kW at 415 V, 22 kW at 380...400 V, and 15 kW at 220...230 V — all at 50/60 Hz. The 24 V AC coil means it's intended for control circuits running on low-voltage AC supplies, common in older panel designs or where a separate control transformer steps down from the line voltage. Mounts to a plate — not a DIN rail — so panel layout needs to account for the 281 mm width, 143 mm height, and 130 mm depth. The plate-mount form factor is typical for older TeSys LC4-D assemblies where the starter was bolted directly to a backplate inside the enclosure. Verify the existing mounting holes and clearance before specifying this as a drop-in replacement for a DIN-rail-mounted unit.","metaTitle":"TeSys LC4D50B7 DOL Starter, 50 A, 24 V AC Coil, Obsolete","metaDescription":"TeSys LC4D50B7 DOL starter, 50 A rated operational current, 24 V AC coil, obsolete.
