Schneider Electric LUCL05FU TeSys U Magnetic Control Unit 1.25-5 A 110-240 V AC Motor Starter Module

The Schneider Electric LUCL05FU is a TeSys U magnetic control unit giving short-circuit protection only, adjustable from 1.25 to 5 A. Plugged into a LUB12, LUB32, or LUB38 power base, it is intended for installations where an upstream variable speed drive or soft starter already provides motor overload protection, completing a disconnect/short-circuit function for 3-phase motors up to 1.5 kW at 400 V, controlled from a 110-240 V AC / 110-220 V DC supply.

Selection Notes

The LUCL05FU shares the LUCL05BL's 1.25-5 A short-circuit-only protection for use downstream of a drive or soft starter, wired instead for a 110-240 V AC / 110-220 V DC control supply. Because it carries no thermal curve, the supply-voltage choice has no bearing on protection coordination; pick it purely to match the panel's existing control circuit. Use an LUCA or LUCB unit instead on any motor that is not already protected by a drive or soft starter.
