Schneider Electric LD4LC30H5 Contactor

Schneider Electric LD4LC30H5 is a 3-pole contactor with a 30 A (AC-3) rating and 3 NO main contacts, built to switch three‑phase motors in industrial power circuits. Designed for 208–240 V AC control (50/60 Hz) and a maximum operating voltage of up to 690 V AC, it supports motor starting and stopping in automation systems such as conveyors, pumps, compressors, HVAC equipment, and material handling lines. Its 10 HP rating at 230 V (3‑phase) and 25 HP at 460 V (3‑phase), panel-mountable design, and the option for auxiliary contacts make it suitable for equipment replacement, control panel retrofits, and new machine installations in manufacturing and process control environments. Common replacements include Schneider Electric LUB32 with TeSys Ultra control unit, Allen‑Bradley 140U‑K‑D32, and Siemens 3RA6232.
