Product Description
It is part of the LS (formerly LG Industrial Systems) Metasol series, known for reliability and precision in industrial motor control. The relay features a current range of 6 to 9 amperes, making it suitable for small to medium-sized motors in various applications. This relay operates on the bimetallic principle, where heat generated by motor current causes bending of a bimetallic strip, eventually tripping the contact mechanism. It offers adjustable current settings within the specified range, allowing fine-tuning to match the motor's full-load current. The MT-32 includes a test button, stop button, and an automatic/manual reset selector, providing flexibility in control and maintenance. Designed for direct mounting to LS magnetic contactors (e.g., MC-32 series) or as a standalone unit with appropriate terminals, the MT-32 ensures seamless integration into existing motor control panels. Its compact size and robust construction comply with international standards such as IEC 60947-4-1 and UL 508, ensuring safety and performance in demanding industrial environments. The LS MT-32(6-9A) is a thermal overload relay designed for protecting three-phase AC motors against overload, phase loss, and prolonged starting.
Basic Product Information
- Bimetallic overload protection with phase loss sensitivity
- Test and stop buttons for easy operation
- Automatic and manual reset modes
- Direct mounting to LS MC-32 series contactors
- Compact and robust design for industrial use
- Adjustable current range: 6-9 A
Technical Specifications
Version & Model Difference
The MT-32 series includes various current ranges (e.g., 1.6-2.5A, 2.5-4A, 4-6A, 5-8A, 6-9A, 7-10A, 9-13A, 12-18A). The (6-9A) version is specifically calibrated for motors with full-load current between 6 and 9 amperes. Other versions differ only in the current adjustment range; the physical dimensions and mounting compatibility remain the same across the series.
