## Summary description

The LSiS MT-32 3.3A M-SOL is a reliable thermal overload relay designed for motor protection. It features an adjustable current range of 2.5 to 4A, ensuring precise protection against overloads and phase failures. This compact device is essential for industrial electrical control systems, providing safety and operational stability for electric motors in various applications.

## Long description

The LSiS MT-32 3.3A M-SOL is a professional-grade thermal overload relay engineered to provide robust protection for electric motors. This device is specifically designed to monitor current flow and disconnect the circuit in the event of an overload or phase failure, thereby preventing damage to motor windings and extending the operational lifespan of your equipment. Its compact design allows for efficient integration into various industrial electrical control panels and motor starter assemblies.
Advantages
This thermal overload relay offers high precision in current monitoring, allowing for a customizable setting range between 2.5 and 4 amperes. The device is built to withstand demanding industrial environments, ensuring consistent performance and reliability. By providing rapid response times during fault conditions, it minimizes the risk of motor burnout and costly downtime. Its straightforward installation process and compatibility with standard contactors make it a versatile solution for modern electrical systems.
Suitable for
Industrial motor control centers
HVAC system motor protection
Conveyor belt drive systems
Pump and compressor motor circuits
General-purpose industrial automation
When it may not be suitable
This relay is not intended for use in circuits exceeding its specified current range of 2.5 to 4 amperes. It is also not suitable for applications requiring protection against short-circuit currents, as it is designed specifically for thermal overload and phase loss protection rather than instantaneous fault clearing.
Key specifications
Adjustable current range: 2.5A to 4A
Protection type: Thermal overload and phase failure
Device series: MT-32
Application: Motor protection
How to use
The LSiS MT-32 3.3A M-SOL is designed to be mounted directly onto a compatible contactor or via a separate DIN-rail mounting kit. Once installed, the current setting dial should be adjusted to match the full-load amperage rating of the motor being protected. After the wiring is secured according to the electrical schematic, the device can be set to manual or automatic reset mode depending on the specific operational requirements of the system.
What to consider before purchase
Verify the full-load current rating of your motor falls within the 2.5-4A range.
Ensure compatibility with your existing contactor model.
Check the environmental conditions of the installation site to ensure they meet the device's operating specifications.
Usage recommendations
Always ensure that the power supply is disconnected before installing or adjusting the relay settings to prevent electrical hazards. Regularly inspect the device for signs of wear or thermal damage to maintain optimal protection levels.
