Havells Thermal Over Load Relay IHHR33

The Havells Thermal Overload Relay IHHR33 is an essential component used in electrical systems to safeguard motors from damage caused by excessive current or overload conditions. It is typically employed in conjunction with contactors and motor starters to provide comprehensive motor protection in various industrial and commercial applications.

Key features and functionalities of the Havells Thermal Overload Relay IHHR33 include:

1. Current Sensing: The IHHR33 relay continuously monitors the current passing through the motor. If the current surpasses the predetermined threshold for an extended duration, indicating an overload situation, the relay activates protective measures.

2. Adjustable Settings: This relay allows for the adjustment of current settings to match the specific requirements of the connected motor. This adaptability enables precise customization based on the motor's characteristics and the demands of the application.

3. Trip Class Options: The IHHR33 relay offers multiple trip classes (such as Class 10, Class 20) to cater to different overload conditions effectively. Each trip class has its distinct time-current characteristics to suit diverse motor protection needs.

4. Manual/Automatic Reset: Users can choose between manual and automatic reset options after a trip event. Manual reset requires human intervention to restore operation, while automatic reset initiates the reset process automatically once the overload condition clears.

5. Compact Design: Designed to fit seamlessly within control panels and motor control centers, the IHHR33 relay features a compact and space-saving design, facilitating easy installation and integration into electrical systems.

6. Reliable Performance: Constructed with high-quality materials and equipped with advanced protective features, the Havells Thermal Overload Relay IHHR33 ensures reliable performance and effective motor protection, even in demanding industrial environments.

In summary, the Havells Thermal Overload Relay IHHR33 is crucial for preventing motor damage due to overcurrent, enhancing operational safety, reducing downtime, and extending the lifespan of electrical equipment.
