Industrial Motor Protection Module

The Schneider Electric LUCB05FU is an overload module designed for three-phase motor circuits in industrial automation panels. It protects motors by monitoring current and tripping on overload conditions within the adjustable range. The unit suits maintenance engineers and panel builders who need reliable motor protection integrated with TeSys Ultra starters.

Fits TeSys Ultra Starters With Wire Leads

This module connects directly to compatible TeSys Ultra power bases using wire-lead terminals and operates on a 110 to 240 V AC/DC control coil voltage. It handles a maximum line voltage of 690 V AC and covers motor current settings from 1.25 A to 5 A. The manual reset function requires operator intervention after a trip, ensuring fault investigation before restart.

Certified For Global Compliance And Green Premium

The module carries UL Listing, CCC, CE, CSA C22.2, EAC and ATEX certifications plus IEC/EN 60947-6-2 compliance. Green Premium status confirms RoHS and REACH conformity for restricted-substance regulations. It cross-references Grainger part numbers 5AB63, 5AB64, 5AB66 and 5AB68 for easy identification in existing bills of material.

Questions about this item

At what current does the overload module trip first during sustained operation?

The module trips when the motor current exceeds the 5 A maximum adjustment setting under continuous load.

How much heat or noise does the unit produce when running all day?

As a solid-state overload relay without moving parts or fans, it generates negligible audible noise and minimal heat during 24-hour operation.

Which TeSys Ultra components must already be installed for this module to work?

It requires a compatible TeSys Ultra power base and control unit; Grainger part numbers 5AB63, 5AB64, 5AB66 or 5AB68 confirm the matching base.
