Product Description
It provides reliable protection against overload, phase loss, and phase unbalance. The relay is part of the LS (formerly LG Industrial Systems) Metasol series, known for its durability and precision. The MT-32 has an adjustable current range of 1.6 to 2.5 amperes, making it suitable for small to medium-sized motors. It features a differential mechanism for phase-loss sensitivity and a manual/automatic reset function. The relay is compact and DIN-rail mountable, simplifying installation in control panels. It is designed to work with LS magnetic contactors, particularly the GMC series, ensuring seamless integration in motor control circuits. The MT-32 complies with international standards such as IEC 60947-4-1 and UL 508, guaranteeing safety and performance. With a robust construction and high electrical endurance, it is ideal for continuous operation in harsh industrial environments. The relay also offers a test button and an indicator for trip status, aiding in maintenance and troubleshooting. The LS MT-32 is a thermal overload relay designed for motor protection in industrial applications.
Basic Product Information

Technical Specifications
Version & Model Difference
The MT-32 series includes various current ranges (e.g., 0.1-0.16A, 0.16-0.25A, ... up to 30-40A). The 1.6-2.5A version is specifically for small motors. Compared to newer LS models like the MT-63 or electronic overload relays, the MT-32 offers basic thermal protection with a bimetallic strip, while newer versions may include more advanced features like digital displays and communication. However, the MT-32 remains popular for its simplicity and cost-effectiveness.
