Product Details
Schneider Electric LRD1521 - TeSys LRD thermal overload relay, 18A/690V, thermal setting range 12-18A, tripping class 20, for protection of 3-phase motors 7.5kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustment dial, a manual-automatic reset selector, a test selector for simulation of a tripping, reset and stop buttons, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signaling. Settings are protected by a transparent cover lockable by sealing. Connection by screw clamp terminals, it connects directly to the bottom terminals of 3-pole contactors LC1D09-D38. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD7B105 (to be ordered separately). Multi standards certified (IEC, UL, CSA, Marine), Green Premium compliant (RoHS/REACh). We are dedicatedly involved in providing an excellent quality products at Electrihub.

Smooth ordering process and quick delivery. This Schneider Over Load Relay (LRD1521) is authentic and works exactly as required. Will buy again from RAS Electrihub.
We always trust Schneider for protection devices. This Over Load Relay was available in stock on RAS Electrihub at a competitive price. Support team helped with cross-checking the model compatibility.
Bought the LRD1521 from Electrihub for our overseas plant – straightforward to install and adjust, the device responded perfectly during overload tests. Customer service from Electrihub deserves 5 stars for guiding us on specs. The price is justified by the quality, and it's reassuring to get real Schneider warranty.
Satisfied with how reliably it operates in our plant, recommended for industrial setups.
Set up quickly, good performance so far, very satisfied.
