Schneider Electric LRD4369 TeSys Deca Thermal Overload Relay \u2013 110\u2026140A, Class 10A, 75kW @ 400V Motor Protection<\/h2>\n

Manufacturer:<\/strong> Schneider Electric
\nModel:<\/strong> LRD4369
\nType:<\/strong> Differential Thermal Overload Relay
\nSeries:<\/strong> TeSys LRD \/ TeSys Deca
\nThermal Protection Adjustment Range:<\/strong> 110\u2026140 A
\nTripping Class:<\/strong> Class 10A
\nMotor Power (AC\u20113 @ 400V):<\/strong> 75kW
\nRated Insulation Voltage (Ui):<\/strong> 1000 V
\nAuxiliary Contacts:<\/strong> 1 NO + 1 NC
\nApplication:<\/strong> Motor overload and phase failure protection in industrial applications<\/p>\n

The Schneider Electric LRD4369 is a differential thermal overload relay from the TeSys Deca series, designed for reliable protection of 3\u2011phase motors against overloads and phase failures. With a thermal adjustment range of 110\u2026140 A and a Class 10A tripping characteristic, it protects motors up to 75kW at 400V. The relay features phase failure and load unbalance detection, a manual\u2011automatic reset selector, a trip test button for simulation, a stop button, and a flag indicator. It connects directly to the bottom terminals of LC1D150 contactors to form a compact starter. Multi\u2011standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine), it is a Green Premium product compliant with RoHS and REACh regulations.[reference:0][reference:1]<\/p>\n
