Schneider Electric LP1-D128 Relay

Schneider Electric LP1-D128 is a four‑pole Telemecanique contactor/relay optimized for 3‑phase motor control, featuring a 24 V coil and a maximum voltage rating of 600 V. It is rated for up to 25 A of load current and supports a 12 A resistive load, with a horsepower range of approximately 2 to 7.5 HP depending on the application and supply. This LP1‑D128 device belongs to Schneider Electric’s TeSys LP1 family and is manufactured by Schneider Electric Telemecanique. The model is listed as discontinued by the manufacturer, so current stock and replacement guidance may require consulting Schneider’s current catalogs or authorized distributors for suitable modern cross‑references. Designed for panel installations in industrial control environments, the LP1‑D128 provides the four power poles needed to switch three‑phase circuits while operating from a 24 V control coil, aligning with common control schematics in automation applications. When selecting a replacement or cross‑reference, verify coil voltage, maximum operating voltage, load current rating, and the four‑pole configuration to ensure compatibility with your existing wiring and three‑phase load requirements.
