Telemecanique lh4n125qn7 Soft Starter

Description:

The Telemecanique LH4N125QN7 soft starter is a solid-state motor starter rated for 22 A at 380–415 VAC, designed to provide controlled starting and stopping of three-phase asynchronous motors. Commonly installed in pumps, conveyors, compressors, fans, HVAC systems, and industrial machinery where reduced mechanical stress and lower motor starting current are required. Maintenance teams, OEMs, and system integrators use this soft starter for equipment replacement, retrofit projects, and motor control system upgrades.

Applications:

The LH4N125QN7 soft starter is designed to improve motor startup performance by limiting inrush current and reducing mechanical wear on driven equipment. It is widely used in manufacturing facilities, water treatment plants, material handling systems, process automation, HVAC installations, and pumping applications where smooth acceleration helps extend equipment life and improve system reliability.
