Reliable Thermal Overload Relays for Motor Protection – Buy Genuine Products at Eleczo
Need dependable protection to prevent motor overload and overheating? Eleczo India Private Limited offers a wide selection of Thermal Overload Relays designed to help maintain safe and stable motor operation in industrial systems. Our range includes trusted options from leading manufacturers such as ABB, Schneider Electric, Siemens, and Lauritz Knudsen(L&T), known for reliable performance and long service life. These relays are built to detect overload conditions early and disconnect the circuit before damage occurs. Whether you need solutions for smaller motors or demanding industrial applications, Eleczo provides genuine products, quick availability, and competitive thermal overload relay price in India.
In industrial motor control systems, managing overload conditions is essential to prevent premature motor failure and costly downtime. A thermal overload relay is specifically designed to monitor the current flowing through a motor and respond when it exceeds the safe operating limit for an extended period. By sensing the heat generated due to excessive current, the relay triggers a trip mechanism that disconnects the motor circuit, protecting the windings from thermal damage. This form of protection is widely used in motor starter assemblies alongside contactors to maintain stable and safe operation across applications such as pumps, conveyors, compressors, and HVAC equipment. At Eleczo India Private Limited, businesses can source reliable thermal overload relays engineered to deliver accurate protection and long-term operational safety in demanding industrial environments.
Key Industrial and Commercial Applications of Thermal Overload Relays
Thermal overload relays are widely used wherever electric motors operate under varying loads or continuous duty cycles. They play a crucial role in protecting motors from overheating, helping maintain safe operation and reducing the risk of unexpected equipment failure.

People Also Ask: Top Questions & Answers
Choose a relay whose adjustable current range matches the motor’s full-load current rating. Also verify trip class, mounting compatibility, and coordination with the contactor used in the motor starter.
Trip classes such as Class 10, 20, or 30 determine how quickly the relay responds to overload. Selection depends on the motor starting time and application load characteristics.
Most relays are designed to match specific contactor series from the same manufacturer. Always verify mechanical mounting and electrical compatibility before installation.
Industrial thermal overload relays typically cover ranges from 0.1A up to 630A depending on the model. This allows protection for small motors as well as heavy-duty industrial drives.
Manual reset requires operator intervention after a trip, improving safety in critical applications. Automatic reset restores operation once the relay cools down and current returns to normal levels.
They are widely used in manufacturing plants, water treatment systems, HVAC equipment, conveyor systems, pumps, and compressors where motors operate continuously.
Price depends on brand, ampere range, trip class, mounting configuration, and compatibility with contactor series. Higher current ratings and advanced protection features typically increase cost.
Industrial buyers can source reliable relays from Eleczo India Private Limited, which offers models from leading brands like ABB, Siemens, Schneider Electric, and Lauritz Knudsen.
