LRD4369 Schneider

LRD4369 is a TeSys LRD thermal overload relay from Schneider Electric to be used with a TeSys D contactor. It protects motors 63kW@400V thanks to a thermal range 110-140A, a tripping class 10A and phase unbalance protection. LRD4369 is a TeSys LRD thermal overload relay from Schneider Electric for direct mounting on TeSys D contactors. With a thermal setting range 110-140A, a tripping class 10A and phase unbalance detection, it protects motors 63kW@400V. It provides manual test & reset buttons, automatic reset, trip auxiliary contact and flag indicator. Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC, Marine). Thermal overload protection relay, bimetallic type, with phase unbalance protection (differential). Direct mounting on the bottom terminals of a Tesys contactor LC1D150 to form a compact starter. Light and compact, 120mm wide. Temperature compensated for a good accuracy of the protection. Manual control with test & reset buttons, manual / automatic reset selector. Trip signaling with 1NO+1NC auxiliary contacts and trip flag indicator. Can be completed with terminal blocks for separate mounting (LAD7B, LAD96) and remote control devices (LAD703, LA7D03).

"Helping us move projects forward"

With supply chain issues increasingly affecting our business, PLC Direct has been there for us to supply the PLC products we need, when we need it. If they don't have it readily available, they find it and provide it quickly and reliably. This has helped us move forward with several projects that would have otherwise taken us many, many months to complete.
