The Havells Thermal Over Load Relay IHHR13CP is a reliable and efficient device that protects electric motors from overload and single phasing. It is a triple pole relay with a current rating of 6-9 Amp. It is suitable for use with HGS9, HGS12, and HGS18 contactors.
The IHHR13CP thermal overload relay works by monitoring the current flowing through the electric motor. If the current exceeds the set overload limit for a certain period of time, the relay will trip, disconnecting the motor from the power supply. This prevents the motor from overheating and burning out.
The IHHR13CP thermal overload relay is also sensitive to single phasing. Single phasing occurs when one of the three phases of a three-phase power supply fails. This can cause the motor to overheat and fail. If the IHHR13CP detects single phasing, it will trip the motor, preventing damage.
Features
- Reliable and efficient protection against overload and single phasing
- Triple pole relay with a current rating of 6-9 Amp
- Suitable for use with HGS9, HGS12, and HGS18 contactors
- Temperature compensated for accurate tripping
- Easy to install and use
- Compact design
Benefits
- Protects electric motors from damage due to overload and single phasing
- Extends the life of electric motors
- Reduces maintenance costs
- Improves safety
Applications
The Havells Thermal Over Load Relay IHHR13CP is suitable for use with a wide range of electric motors, including:
- Industrial motors
- Commercial motors
- Domestic motors
- Motors used in pumps, fans, compressors, and other equipment
Installation
The Havells Thermal Over Load Relay IHHR13CP is easy to install. It can be mounted on the contactor or on a separate mounting plate. The relay is connected to the contactor and the motor using the supplied terminals.
Usage
Once the IHHR13CP thermal overload relay is installed, it should be set to the appropriate overload current and tripping time. The overload current setting should be slightly above the normal operating current of the motor. The tripping time setting should be set so that the relay trips before the motor overheats.
Maintenance
The Havells Thermal Over Load Relay IHHR13CP requires very little maintenance. The only regular maintenance required is to check the terminals for tightness and to clean the contacts.
Conclusion
The Havells Thermal Over Load Relay IHHR13CP is a reliable and efficient device that protects electric motors from overload and single phasing. It is easy to install and use, and it requires very little maintenance. We highly recommend the IHHR13CP thermal overload relay for use with a wide range of electric motors.
