No issues after several weeks, good service from Electrihub.

Priya L Oct 29, 2025

Been using this relay for months, consistent protection for motors. Settings adjustment is straightforward, solid Schneider build as usual.

Manoj S Oct 29, 2025

Works as described, reliable for daily operations.

Rahul S Oct 29, 2025

We replaced older relays with the LR3D166 for automation upgrades. It's easy to wire, the thermal range covers most motor sizes, and the unit doesn't overheat in tough conditions. What makes it uniquely valuable is compatibility with Schneider contactors, allowing modular expansion when we scale up operations. Shipping to UK was fast, and the quality assurance gives peace of mind.
