Schneider Electric LH4N125QN7 Soft Starter Module

Schneider Electric's Telemecanique LH4N125QN7 Soft Starter Module (MPN LH4N125QN7) delivers controlled startup for three-phase asynchronous motors at 380–415 VAC with a rated operating current of 22 A. It uses a voltage ramp starting method with an adjustable start time from 1 to 5 seconds and includes an integrated bypass for panel-mount installations. Rated for motors up to 11 kW (15 HP) and compatible with three-phase motor control systems, this soft starter helps limit inrush current and reduce mechanical wear in pumps, conveyors, compressors, fans, HVAC systems, and other industrial equipment. Designed as an OEM direct replacement, it is commonly used in retrofit projects and motor control system upgrades.
