Contact us... Price & Availability Contact us for pricing / 询价 It is part of the LS (formerly LG Industrial Systems) Metasol series, widely used in industrial motor control panels. The relay features a bimetallic strip mechanism that accurately simulates motor heating, providing reliable protection in ambient temperatures up to 55°C. Its compact design allows direct mounting to LS magnetic contactors (e.g., GMC series) or independent installation via terminal blocks. This model covers an adjustable current range of 9 to 13 amperes, making it suitable for motors rated approximately 4.5 to 6.5 kW at 400V AC. The relay offers a trip class of 10A, ensuring fast response to locked rotor conditions while allowing normal starting currents. It includes a manual/auto reset selector, a test button, and a stop button for convenient operation and troubleshooting. The MT-32 is designed to meet IEC 60947-4-1 and UL 508 standards, ensuring global acceptance. With a robust construction and high electrical endurance, the MT-32(9-13A) ensures long service life even in harsh industrial environments. Its screw terminals accept wires up to 10 mm², and the device can be installed on 35mm DIN rails or directly onto contactors. The relay is a direct replacement for older LG GTH-32 models and is compatible with LS GMC-32, GMC-40, and GMC-50 contactors, making it a versatile choice for panel builders and maintenance teams. The LS MT-32(9-13A) is a thermal overload relay designed for protecting three-phase AC motors against overload, phase loss, and prolonged starting conditions. Basic Product Information Trip class 10A for fast response to locked rotor conditions Manual/auto reset selector for flexible operation Test and stop buttons for easy commissioning and troubleshooting Direct mounting to LS GMC series contactors or independent installation Phase loss protection and ambient temperature compensation Compact design with IP20 protection degree Adjustable current range 9-13A for precise motor protection Technical Specifications Version & Model Difference The MT-32 series is the successor to the older LG GTH-32 series. The MT-32(9-13A) features a more compact design, improved ambient temperature compensation, and a wider range of compatible contactors. Compared to earlier versions, it offers a higher degree of protection (IP20) and meets the latest IEC standards. The current range 9-13A is specifically calibrated for motors in the 4-6.5 kW range at 400V, whereas other MT-32 variants cover different ranges (e.g., 1.6-2.5A, 4-6A, 18-25A). Application Scenarios Can the MT-32(9-13A) be used with LS GMC-32 contactor? Yes, the MT-32 is designed for direct mounting on LS GMC-32, GMC-40, GMC-50, and GMC-65 contactors. It can also be mounted independently on a DIN rail. Does the MT-32 provide phase loss protection? Yes, it provides phase loss protection as per IEC 60947-4-1, tripping the relay if one of the three phases is lost. What is the trip class of the MT-32(9-13A)? The trip class is 10A, meaning it will trip within 10 seconds at 7.2 times the current setting, providing fast protection against locked rotor conditions. What is the adjustable current range of the LS MT-32(9-13A)? The MT-32(9-13A) has an adjustable current range from 9 to 13 amperes, allowing you to set the trip current according to the motor's full-load current.
