The Havells 3 Pole Thermal Overload Relay is a high-performance device designed to protect electrical circuits and equipment from overheating and potential damage caused by excessive current. Engineered with precision and reliability in mind, this overload relay provides robust protection for three-phase electrical systems, making it an essential component in industrial and commercial applications where motor protection is critical. The relay operates based on the principle of thermal expansion, where an internal bimetallic strip responds to the heat generated by overcurrent conditions. As the temperature rises, the strip bends and activates the relay mechanism to disconnect the circuit, preventing damage to motors and other connected equipment. The Havells 3 Pole Thermal Overload Relay is known for its durability and accuracy, featuring a wide range of adjustable settings that allow for precise calibration to suit various load requirements. The relay’s design includes an easily accessible adjustment dial, enabling users to set the desired trip current level with ease. This flexibility ensures that the relay can be tailored to match the specific characteristics of the motor or equipment it is protecting. Additionally, the relay is equipped with a manual reset function, allowing users to quickly and conveniently restore operation once the overcurrent condition has been addressed and the system has cooled down. Constructed with high-quality materials, the Havells 3 Pole Thermal Overload Relay offers exceptional resistance to mechanical wear and environmental factors, ensuring reliable performance in demanding industrial environments. Its compact design and modular construction facilitate straightforward installation and integration into existing control panels and motor starter assemblies. The relay's clear and precise trip indicator provides immediate feedback on overload conditions, helping to streamline troubleshooting and maintenance processes.

The Havells 2 Pole Thermal Overload Relay is a sophisticated and essential device designed to protect single-phase electrical circuits and equipment from the risks associated with overcurrent and overheating. This relay operates on the principle of thermal expansion, utilizing a bimetallic strip that responds to increased temperatures caused by excessive current flow. When the strip heats up beyond a predetermined threshold, it bends and activates the relay mechanism, thereby disconnecting the circuit to prevent potential damage to motors and other electrical components. This proactive approach helps to safeguard the integrity of the electrical system and prolong the lifespan of the equipment. Engineered for precision and reliability, the Havells 2 Pole Thermal Overload Relay features an easily adjustable dial that allows users to set the relay's trip current to match specific load requirements. This adjustability ensures that the relay can be customized to protect various types of motors and equipment effectively. The relay also includes a manual reset function, which simplifies the process of restoring the circuit once the overload condition has been resolved and the system has cooled down. The device is constructed with high-quality materials, ensuring durability and resistance to mechanical wear and environmental stress. Its compact and modular design facilitates straightforward installation and integration into existing control panels and motor starter assemblies. Additionally, the relay's clear trip indicator provides immediate visual feedback on overload conditions, aiding in swift troubleshooting and maintenance.
