Havells Thermal Over Load Relay IHHR23

The Havells Thermal Overload Relay IHHR23 is a vital component in electrical systems, specifically designed to protect motors from damage caused by overcurrent or overload conditions. It is commonly used in conjunction with contactors and motor starters to provide comprehensive motor protection in industrial and commercial applications.

Here are some key features and functionalities of the Havells Thermal Overload Relay IHHR23:

1. Current Sensing: The IHHR23 relay continuously monitors the current flowing through the motor. If the current exceeds the preset threshold for an extended period, indicating an overload condition, the relay initiates a protective action.

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

3. Trip Class Options: The relay offers various trip classes (such as Class 10, Class 20) to provide flexibility in responding to different overload conditions. Each trip class has its specific time-current characteristics to suit diverse motor protection requirements.

4. Manual/Automatic Reset: The IHHR23 relay supports both 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 within control panels and motor control centers, the IHHR23 relay features a compact and space-saving design, facilitating easy installation and integration into electrical systems.

6. Reliable Performance: With high-quality construction and advanced protective features, the Havells Thermal Overload Relay IHHR23 ensures reliable performance and effective motor protection, even in demanding industrial environments.

Overall, the Havells Thermal Overload Relay IHHR23 plays a crucial role in preventing motor damage due to overcurrent, enhancing operational safety, reducing downtime, and extending the lifespan of electrical equipment.
