Schneider Electric LRD3353
Thermal Overload Relay, 23 to 32 A, Class 10A
Product Description
This thermal overload relay is specifically engineered for use with contactors rated between 80 A and 95 A, effectively forming a motor starter. It functions by detecting overcurrents within the motor supply lines; upon detection, it collaborates with the contactor to disconnect power, thus safeguarding the motor windings from damage.
With an adjustable trip current rating spanning from 23 to 32 amperes, this device adheres to Class 10A standards, ensuring reliable thermal protection for motor applications. The relay is multi-standard certified, including IEC, UL, and CSA, and meets various environmental compliance regulations such as RoHS and REACH, contributing to its Green Premium status.
Notable specifications include a dielectric strength of 2.2 kV and a rated impulse withstand voltage of 6 kV, enabling robust performance under demanding conditions. The relay operates effectively in ambient temperatures ranging from -20°C to 60°C without derating, and it features an IP20 degree of protection, conforming to IEC standards.
