Electronic relay for TeSys motor 5-25A 200/240VAC LR97D25M7

Electronic overload relay TeSys LR97D – reliable motor protection

The LR97D25M7 electronic relay is part of the TeSys LR97D series from Schneider Electric, designed to protect electric motors from overload. The device offers current adjustment in the range of 5-25A and is adapted to operate in 200/240VAC networks. Its compact design (45mm width) facilitates integration with various motor control and starting systems. This relay finds wide application in both industrial installations and commercial applications, providing effective protection and increasing the reliability of devices.

Functionality and design for professionals and users

The LR97D25M7 relay features the ability to lock settings by sealing the transparent cover, preventing accidental changes to operating parameters. It has three knobs for precise adjustment of protection parameters, allowing adaptation to specific application requirements. Automatic and manual reset allow for quick restoration of device operation after a failure. Direct mounting simplifies installation and minimizes the need for additional mounting elements. The reset signal input allows for remote device reset, which is particularly useful in automated systems.

Key features and benefits

• Adjustable current range: Allows precise adjustment of protection to the load characteristics (5-25A).
• Compact dimensions: 45 mm width allows for easy integration with existing installations and switchboards.
• Settings lock: Protects against unauthorized changes to operating parameters.
• Automatic and manual reset: Enables quick restoration of device operation after a failure.
• Universal control voltage: Adapted to operate in 200-240VAC networks, which increases its flexibility of use.
• Screw connection: Provides solid and reliable connection of wires.
• Status indication: Has one changeover auxiliary contact (1C/O) for signaling the device's operating status.
• Compliance with standards: Ensures safe and reliable operation in various industrial environments.

Technical specifications

The LR97D25M7 relay is characterized by an operating voltage of AC 50/60 Hz in the range of 200-240V and the ability to adjust the current in the range of 5-25A. Its dimensions are 45 mm (width), 64.5 mm (height) and 67.5 mm (depth). The device has a screw connection of the main contacts and a direct mounting method. The type of control voltage is AC, and the tripping class is adjustable, allowing adaptation of the tripping characteristics to the specifics of the load. The lack of normally open or normally closed auxiliary contacts limits its functionality to basic overload protection with the possibility of signaling the status using a single changeover contact.
