The Schneider LA4DC3U is a suppressor module designed to enhance the performance and longevity of electronic systems by mitigating voltage spikes and surges. This component is part of the TeSys product range and is compatible with a variety of Schneider contactors, including the 3-pole LC1D80 to D95 and the 4-pole LC1D40008 to D80008, as well as the 4-pole LP1D80004. Crafted for top mounting and secured by screws, the LA4DC3U employs flywheel diode technology to provide effective suppression across control circuit voltages ranging from 24 to 250 V DC. Its robust design ensures that it can withstand maximum peak voltages up to 1 Uc, making it a reliable choice for demanding industrial environments. The module is lightweight, weighing in at just 0.018 kg, and is engineered to operate within a wide temperature range of -25 to 55 °C, ensuring consistent performance even in extreme conditions. For storage, it can handle temperatures from -40 to 80 °C. The LA4DC3U is recognised for its compliance with international standards, including IEC 60947-5-1, EN 60947-5-1, CSA C22.2 No 60947-5-1, UL 60947-5-1, and GB/T 14048.5, and holds certifications from UL and CSA. It also boasts an IP2X degree of protection according to IEC 60529, which adds to its reliability and safety in operation. This suppressor module is a Green Premium product, indicating its compliance with the latest environmental standards and regulations, such as REACh and EU RoHS. It is free of SVHC (Substances of Very High Concern), toxic heavy metals, and mercury, underlining Schneider Electric's commitment to environmental sustainability and user safety. The Schneider LA4DC3U is a testament to Schneider Electric's dedication to quality, performance, and environmental responsibility, making it an essential component for modern industrial applications that require robust protection against electrical disturbances.
