Square D LUCC32FU – Frequently Asked Questions
1) Can the Square D LUCC32FU control unit be used on its own, or does it need a power base?
It can't work alone. The LUCC32FU is the control and diagnostic half of a TeSys U starter and plugs into an advanced power base, specifically the LUB320 or LUB380, to form a complete starter controller. Order the base separately along with the control unit.
2) What motor current range does the TeSys Ultra LUCC32FU cover?
Rated current Ir is adjustable from 8 to 32A, so you dial the setting to the motor's full load amps rather than stocking a separate relay per motor. It is a 1-phase unit good for motors up to 7.5 kW at 400 to 440V AC, 50/60Hz. If your motor FLA falls outside 8-32A, this is the wrong unit.
3) Will the LUCC32FU protect a three-phase motor?
No. This control unit is built for 1-phase motor applications. For a three-phase load you need the three-phase version of the TeSys U control unit matched to that motor's current range, not the LUCC32FU.
4) What control voltage do I need to wire to the TeSys U LUCC32FU?
Control circuit voltage Uc is 110 to 240V AC or 110 to 220V DC, with operating limits of 88 to 264V AC and 88 to 242V DC. A 120V or 240V control transformer feed works; a 24V control scheme does not.
5) Is the TeSys Ultra LUCC32FU UL listed for use in a US panel?
It is UL Listed and CSA Certified, in both cases to the 60947-4-1 standard with a phase barrier fitted, and CE marked. It also carries EAC, CCC, ATEX, ASEFA and Marine certifications, and meets IEC/EN 60947-6-2.
6) How is the LUCC32FU mounted, and can I swap it without rewiring the panel?
Mounting is plug-in from the front face into the power base. Because the power wiring terminates on the LUB320 or LUB380 base, the control unit can be pulled and replaced from the front without disturbing the panel wiring. The compatibility code is LUCC.
7) Is the LUCC32FU suitable for a 600V industrial panel?
Yes. Rated operational voltage Ue is 690V AC and rated insulation voltage Ui is 690V, with a 6kV rated impulse withstand (Uimp), so a 480V or 600V power circuit is within rating.
8) What protection functions does this TeSys Ultra unit actually provide beyond overload?
Along with thermal overload and short-circuit protection, the advanced control unit provides earth fault protection, phase failure and imbalance protection, and manual reset. Trip threshold is 14.2 x Ir plus or minus 20 percent.
9) Does the LUCC32FU reset itself after a trip?
Manual reset. After a trip the unit stays tripped until someone resets it at the front face, which is what you want where an unattended restart is a safety problem.
10) What enclosure rating does the TeSys U control unit have on its own?
IP20 at the front panel and wired terminals, rising to IP40 at the front panel when the cover is fitted, per IEC 60947-1. IP20 means it is finger-safe but not dust or water protected, so it belongs inside a control cabinet or panelboard.
11) Can the LUCC32FU be installed in an unheated warehouse or a high-altitude site?
Storage ambient is rated -40 to 85 degrees C and the operating altitude limit is 2000 m (6561.68 ft). Above that altitude you have to derate, so for high-elevation installations check the site elevation against the 2000 m figure before specifying.
12) What is the exact part number and where is the TeSys Ultra 8-32A 1-phase control unit made?
The part number is LUCC32FU, a Square D TeSys Ultra advanced control unit, manufactured in France.
