LR9F5369

The LR9F5369 from Schneider Electric is engineered as an electronic thermal overload relay. This component is intended for protecting motors, ensuring they operate within safe limits. With an adjustable thermal protection range set between 90 A and 150 A, it adapts to various load requirements. It operates at network frequencies of 50/60 Hz, which makes it versatile for different installations.

This relay can be directly mounted on contactors or plates, providing easy integration into existing setups. A surge withstand rating of 4 kV enhances its resilience in challenging electrical environments. The device offers a rated operational voltage of 1000 V AC, suitable for industrial applications that require higher voltage ratings. Additionally, it possesses an impressive impulse withstand voltage of 8 kV.

Monitoring current consumption remains efficient, with a no-load condition requirement of 5 mA or less. The relay includes an alarm switching capacity adjustable from 0 to 150 mA, effectively signaling any irregularities in operation. In terms of performance metrics, it maintains a maximum voltage drop of less than 2.5 V while closed, ensuring minimal power loss during operation.

The relay's tightening torque specifications are critical for installation, with control circuit torque set at 1.2 N.m and power circuit torque at 18 N.m. In terms of physical dimensions, the LR9F5369 measures 96 mm in height, 123.5 mm in depth, and 115 mm in width, weighing approximately 0.885 kg. This compact design facilitates efficient placement and management in various applications.
