The Schneider Thermal Overload Relay LRD22 is a versatile and reliable device that protects a.c. circuits and motors against overloads. It has a thermal setting range of 16-24A and a tripping class of 10A. It can be used to protect 3-phase motors up to 11kW at 400V.
The LRD22 has a number of features that make it a reliable and versatile choice for overload protection. These features include:
- Differential device with phase failure (loss) detection
- Manual-automatic reset selector
- Test selector for simulation of a tripping
- Reset and stop buttons
- Flag indicator
- 2 auxiliary contacts (1NO+1NC) for fault signalling
The LRD22 is easy to install and use. It can be mounted on a DIN rail or screwed directly to a contactor. The relay’s settings are protected by a transparent cover that can be locked with a seal.
The LRD22 is a reliable and versatile thermal overload relay that is ideal for protecting a.c. circuits and motors against overloads. It is easy to install and use, and it meets a wide range of international standards.

- Improved safety: The LRD22 can help to prevent fires and other accidents caused by electrical overloads.
- Increased uptime: The LRD22 can help to prevent downtime caused by motor burnout.
- Reduced costs: The LRD22 can help to reduce the cost of repairs and replacements caused by electrical overloads.
If you are looking for a reliable and versatile thermal overload relay, the LRD22 is a great option. It is easy to install and use, and it meets a wide range of international standards.
Here are some additional details about the LRD22’s features:
- Differential device with phase failure (loss) detection: The LRD22’s differential device helps to protect motors from damage caused by unbalanced loads. The device compares the currents in each phase of the motor and trips the relay if the currents are unbalanced.
- Manual-automatic reset selector: The LRD22 has a manual-automatic reset selector that allows you to choose whether the relay will reset automatically after a trip or if you will need to reset it manually.
- Test selector for simulation of a tripping: The LRD22 has a test selector that allows you to simulate a tripping condition. This can be useful for testing the relay’s operation and for troubleshooting motor problems.
- Reset and stop buttons: The LRD22 has reset and stop buttons that allow you to manually reset the relay or stop the motor.
- Flag indicator: The LRD22 has a flag indicator that shows the current status of the relay. The flag is green when the relay is in normal operation, yellow when the relay is tripped, and red when the relay is in test mode.
- 2 auxiliary contacts (1NO+1NC): The LRD22 has 2 auxiliary contacts that can be used for fault signalling. The NO contact will close when the relay trips and the NC contact will open when the relay trips.
The LRD22 is a reliable and versatile thermal overload relay that is ideal for protecting a.c. circuits and motors against overloads. It is easy to install and use, and it meets a wide range of international standards
