Havells Thermal Over Load Relay IHHR13

The Havells Thermal Overload Relay IHHR13 is a protective device designed to safeguard electrical motors from damage caused by overheating due to excessive current flow. It is commonly used in conjunction with contactors to provide comprehensive motor protection in various industrial and commercial applications.

The IHHR13 relay operates based on the principle of thermal sensitivity. It monitors the current passing through the motor and detects any deviation from the set threshold. When the current exceeds the permissible level for an extended period, indicating a potential overload condition, the relay triggers a protective action to disconnect the motor from the power supply.

Key features of the Havells Thermal Overload Relay IHHR13 include:

1. Adjustable Current Setting: The relay allows users to adjust the current threshold to match the specific requirements of the motor being protected.

2. Trip Class Selection: It offers multiple trip classes (e.g., Class 10, Class 20) to provide flexibility in responding to different types of overload conditions.

3. Manual/Automatic Reset: The relay can be configured for manual or automatic reset after a trip event, depending on the application requirements and safety protocols.

4. Compact Design: The IHHR13 relay is designed to be compact and space-saving, making it suitable for installation in control panels and motor control centers.

5. Reliable Performance: Built with high-quality components and advanced technology, the relay ensures reliable operation and effective motor protection in harsh industrial environments.

Overall, the Havells Thermal Overload Relay IHHR13 offers efficient motor protection against overloads, contributing to increased operational safety, reduced downtime, and extended equipment lifespan in industrial and commercial settings.
