Havells Thermal Over Load Relay IHHR73

The Havells Thermal Overload Relay IHHR73 is a crucial device designed to protect motors from damage due to overloading in a wide range of industrial and commercial applications. As an integral part of motor control systems, this relay continuously monitors the electrical current flowing through the motor and activates protective measures when an overload condition is detected.

The IHHR73 employs advanced sensing technology to accurately detect deviations from normal operating currents. When the current exceeds pre-set thresholds for an extended period, indicating an overload situation, the relay promptly intervenes to prevent motor damage. By quickly disconnecting the motor from the power supply, it helps avoid overheating and potential burnout, thus ensuring the safety and longevity of the motor.

One of the key features of the IHHR73 is its adjustable settings, which allow users to customize the protection levels according to the specific requirements of the motor and application. This flexibility enables precise calibration based on factors such as motor characteristics, load demands, and environmental conditions, ensuring optimal performance and reliability.

The relay offers multiple trip class options, including Class 10 and Class 20, each with unique time-current characteristics to effectively address various overload conditions. Additionally, users can choose between manual and automatic reset options after a trip event, providing versatility and convenience in operation.

Constructed with high-quality materials and engineered for durability, the Havells Thermal Overload Relay IHHR73 is easy to install and integrate into motor control panels and switchboards. Its robust performance, advanced protective features, and user-friendly design make it an indispensable component for safeguarding motors and ensuring uninterrupted operation in industrial and commercial settings.
