Manufacturer:<\/strong> Schneider Electric The Schneider Electric LRD4367 is a differential thermal overload relay from the TeSys Deca series, designed for reliable motor protection in industrial applications. With a thermal adjustment range of 95\u2026120A and a Class 10A tripping characteristic, it provides accurate overload protection for 3\u2011phase motors up to 55kW at 400V[reference:0][reference:1]. Featuring phase failure and load unbalance detection[reference:2], a manual\u2011automatic reset selector, and a trip test button for simulation[reference:3], the LRD4367 delivers high safety and operational flexibility[reference:4]. It connects directly to the bottom terminals of LC1D115 and LC1D150 contactors[reference:5], and is multi\u2011standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine)[reference:6], making it suitable for demanding industrial environments worldwide.<\/p>\n Wide Thermal Adjustment Range<\/strong>: Adjustable from 95A to 120A with a precise dial, providing flexible overload protection for a variety of motor applications[reference:7][reference:8].<\/p>\n<\/li>\n Class 10A Tripping<\/strong>: Delivers reliable overload protection for standard motor starting applications, ensuring safe and predictable operation[reference:9][reference:10].<\/p>\n<\/li>\n Phase Failure & Load Unbalance Detection<\/strong>: Provides enhanced motor protection by detecting phase loss and load imbalances, preventing motor damage[reference:11][reference:12].<\/p>\n<\/li>\n Integrated Auxiliary Contacts<\/strong>: Built\u2011in 1 NO + 1 NC auxiliary contacts for remote fault signalling and control circuit integration[reference:13][reference:14].<\/p>\n<\/li>\n Manual\u2011Automatic Reset & Test Functions<\/strong>: Features a selector for manual or automatic reset, a trip test button for simulation, and a stop button for manual intervention[reference:15].<\/p>\n<\/li>\n Easy Installation & Mounting<\/strong>: Direct connection to LC1D115\/D150 contactors, or DIN rail \/ screw fixing with optional terminal block LA7D3064[reference:16].<\/p>\n<\/li>\n Global Compliance & Sustainability<\/strong>: Multi\u2011standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine)[reference:17]; Green Premium product with a lifecycle carbon footprint of 8 kg CO\u2082 eq[reference:18][reference:19].<\/p>\n<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
