The Schneider LR2D3555 is a robust and reliable thermal overload relay designed to provide effective motor protection. Part of the TeSys LRD series, this relay is engineered to safeguard motors by preventing overheating, ensuring operational efficiency and longevity. It operates within a thermal protection adjustment range of 30 to 40 amperes and is classified as a Class 20 device according to IEC 60947-4-1 standards.
This relay is compatible with both AC and DC networks, offering versatility in various industrial applications. It features a rated insulation voltage of 690 V, making it suitable for demanding electrical environments. The LR2D3555 is equipped with a tripping threshold of 1.14 ± 0.06 Ir, providing precise and reliable protection against phase failure and overload conditions.
Designed for easy integration, the relay can be mounted on a plate or rail with specific accessories, or directly under a contactor. It includes both normally open (NO) and normally closed (NC) auxiliary contacts, enhancing its functionality in control circuits. The device is built to withstand ambient temperatures ranging from -20 to 60 degrees Celsius without derating, ensuring consistent performance in diverse conditions.
With an IP20 degree of protection, the Schneider LR2D3555 is suitable for use in environments where basic protection against dust and accidental contact is required. Its compact dimensions and straightforward installation make it an ideal choice for engineers and technicians seeking a reliable solution for motor protection.
