I have been ordering from Ras Electrihub for a while, and this LRE21 Over Load Relay purchase was another great experience. Original parts and fast shipping.

Suresh Raina Apr 29, 2026

High-quality Over Load Relay from Schneider. I bought the LRE21 from Ras Electrihub and it was a seamless experience from order to installation.

Manoj S Oct 29, 2025

We replaced older relays with the LRE21 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.

Ashwin N Oct 29, 2025

Solid product, installation was hassle-free and quality met expectations.

Rebecca V Oct 29, 2025

Easy wiring and sturdy build, will buy again for future projects.

Deepika V Oct 29, 2025

Satisfied with how reliably it operates in our plant, recommended for industrial setups.
