Application

This thermal overload relay is primarily used in industrial automation and control systems for motor protection in applications such as pumps, fans, conveyors, and machine tools. It prevents motor damage from overloads, phase failure, and prolonged starting times.

Country of Origin

Made in France.

CO2 Impact

Choosing this reused component saves an estimated 6.0 kg of CO2, which is comparable to the emissions from driving a standard car for 30 kilometers.

Availability

In stock. This unit is a new surplus item in its original box.

FAQ

What is the difference between Trip Class 10A and Trip Class 20?

Trip Class 10A, like on this LRD32 relay, means the device will trip within 10 seconds at 7.2 times the set current. This is suitable for standard motor start-ups. Class 20 allows for a longer starting time (up to 20 seconds) and is used for heavy-duty applications with high-inertia loads.

Can this LRD32 relay be mounted independently, or does it require a contactor?

The LRD32 is designed for direct mounting onto Schneider Electric TeSys D contactors (models LC1D25, LC1D32, and LC1D38). For independent mounting, a separate terminal block, such as the LAD7B106, is required.

How does the ambient temperature affect the performance of the LRD32?

This is a bimetallic thermal overload relay, and its tripping characteristics are affected by ambient temperature. The LRD32 is temperature-compensated for operation between -20 deg C and +60 deg C. For temperatures outside this range, derating factors provided by Schneider Electric should be applied for accurate protection.
