Telemecanique LR2-D1307 Thermal Overload Relay

The Telemecanique LR2-D1307 is a three‑pole thermal overload relay that provides adjustable overload and phase‑failure protection for 3‑phase motors within TeSys D motor control systems. It offers an adjustable current range of 1.6–2.5 A and a 690 VAC rating (600 VAC UL/CSA), safeguarding motors in applications such as motor control centers, conveyors, pumps, compressors, HVAC equipment, and packaging machinery. The relay includes 1 NO + 1 NC auxiliary contacts, screw‑clamp terminals, and mounting options that permit direct mounting to TeSys D LC1D/LC2D contactors (9–32 A), as well as DIN rail or panel mounting. It is designed for compatibility with TeSys D components and provides motor overload and phase‑failure protection with a Class 10A protection rating. The LR2-D1307 is offered as an OEM direct replacement, with common equivalents including Schneider Electric LRD07 and Telemecanique LRD07 for the 1.6–2.5 A range. Used by maintenance teams, OEMs, and system integrators for repair, retrofit, or new motor starter installations in industrial facilities, this relay helps protect motors and extend service life.
