LS MT-32 8.5A M-SOL Thermal Overload Relay 7-10A

The LS MT-32 8.5A M-SOL thermal overload relay is a precision-engineered component designed to provide robust protection for electric motors. By monitoring current flow, this device safeguards equipment against thermal damage resulting from sustained overloads or phase loss conditions. It is built to meet the rigorous demands of industrial automation, offering a reliable solution for maintaining the integrity of electrical circuits and preventing costly downtime.

Advantages

This thermal overload relay offers exceptional reliability through its precise current sensing capabilities and adjustable setting range. Its design ensures rapid response times during fault conditions, effectively disconnecting the circuit before damage occurs to the motor windings. The compact construction allows for seamless integration into existing control panels, while the durable materials used in its manufacturing guarantee long-term operational stability even in challenging industrial environments.

Suitable for

• Industrial motor control centers
• Automation systems and machinery
• HVAC equipment protection
• Conveyor belt motor management
• Pump and compressor control circuits

When it may not be suitable

This relay is specifically designed for thermal overload protection and is not intended for use as a primary short-circuit protection device, such as a fuse or circuit breaker. It should not be used in applications where the motor current consistently falls outside the specified 7 to 10A adjustment range.

Key specifications

• Adjustable current range: 7 to 10A
• Protection type: Thermal overload and phase failure
• Mounting type: Direct contactor mounting
• Operating environment: Industrial automation

How to use

The relay is designed to be mounted directly onto a compatible contactor. Once installed, the current setting should be adjusted using the dial on the front of the unit to match the full-load current rating of the motor being protected. Ensure that all electrical connections are tightened to the specified torque values to prevent overheating at the terminals. After installation, perform a test to verify that the auxiliary contacts function correctly when the test button is pressed.

What to consider before purchase

• Verify that the motor full-load current falls within the 7-10A range
• Ensure compatibility with the specific contactor model
• Check the environmental conditions of the installation site
• Confirm the required protection features for your specific motor application

Usage recommendations

Regularly inspect the relay for signs of wear or loose connections and perform periodic testing of the trip mechanism to ensure continued motor protection and system safety.
