The TeSys LRD05 by Schneider Electric is a robust thermal overload relay that effectively guards against motor overheating and potential damage. It is engineered to operate within a network frequency range of 0 to 400 Hz. This relay features a thermal overload class designation of Class 10A conforming to the IEC 60947-4-1 standard.
With a tripping threshold calibrated at 1.14 ± 0.06 Ir, the device accurately responds to conditions that might lead to overheating, thereby safeguarding motor assets. The design incorporates an auxiliary contact arrangement, consisting of one normally open (NO) and one normally closed (NC) contact, enhancing its utility in various applications.
Temperature fluctuations can be accommodated with a working range extending from -4°F to 140°F (-20°C to 60°C), making it suitable for diverse operational environments. The physical dimensions of the LRD05 are compact, with a height of 2.6 inches (66 mm), a width of 1.8 inches, and a depth of 2.8 inches, which makes it easy to install in confined spaces. Additionally, it weighs approximately 0.273 pounds.
In terms of dielectric performance, the relay exhibits a dielectric strength of 1.89 kV at 50 Hz according to IEC 60947-1 standards. It also withstands impulse voltages up to 6 kV. The LRD05 is rated for a maximum operational voltage of 690 V and has a rated insulation voltage ([Ui]) of 600 V per CSA standards, ensuring compliance with relevant electrical safety regulations. Furthermore, its climatic endurance is classified according to IACS E10, demonstrating resilience under various environmental conditions.
