Telemecanique LR2D1514 Thermal Overload Relay

The Telemecanique LR2D1514 thermal overload relay is a 3-pole motor-protection device designed to work with TeSys D contactors. It provides adjustable overload protection with a current range of 7–10 A and Class 20 tripping characteristics, guarding three-phase motors against overload and phase-loss conditions in industrial motor control systems. This relay is rated for 690 VAC (600 VAC UL/CSA) and includes one normally open and one normally closed auxiliary contact. Mounting options include direct contactor mount, DIN rail, or panel mount with accessories, and it uses screw-clamp terminals for secure connections. Compatible with TeSys D LC1D contactors across several frame sizes (LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, LC1D38), the LR2D1514 serves as an OEM direct replacement for common configurations. Operating temperature range is -20°C to +60°C, and its three-pole design provides reliable motor overload and phase-failure protection within manufacturing facilities, water treatment plants, material handling systems, HVAC equipment, machine tools, and industrial control panels.
