Product details

It is designed to protect a 3-phase motor fed through a variable-speed drive or soft-start/soft-stop unit, which is a specific application: standard motor starters see sinusoidal current, but a drive output carries PWM waveforms with higher peak heating. The LUCL32ES handles that. It is rated for AC-44, AC-43, and AC-41 utilisation categories — AC-44 being the toughest (frequent plugging and inching of slip-ring motors). Motor power capability reaches 15 kW at 400-440 V AC, 15 kW at 500 V AC, and 18.5 kW at 690 V AC. Control voltage is 48 V AC or 48-72 V DC, with a typical inrush of 280 mA and a sealed hold of 45 mA. The unit mounts plug-in to the front face of the TeSys Ultra contactor base — no DIN-rail space consumed beyond the contactor itself. IP20 on the front panel and wired terminals, IP40 on the front face outside the connection zone. Rated insulation voltage is 690 V per IEC 60947-6-2, 600 V per UL 60947-4-1 and CSA C22.2 No 60947-4-1.

The 3 ms immunity to microbreaks means the unit ignores a supply dip of up to 3 ms, which is common on a line with contactor bounce or a brief loss of control power. The 70% / 500 ms immunity to voltage dips (per IEC 61000-4-11) means the control circuit holds in during a sag that would drop out a less tolerant coil. For a commissioning engineer: the opening time is 35 ms with either the LUB32 or LUB38 control-circuit module; closing time is 60 ms with either. That is consistent timing across the range — no surprise when coordinating with upstream protection.

The LUCL32ES carries compliance to EN/IEC 60947-6-2 (the transfer-switch standard that covers motor-protective switching devices), UL 60947-4-1 with phase barrier, and CSA C22.2 No 60947-4-1 with phase barrier. Safe separation of circuits is rated at 400 V SELV between control/auxiliary and main circuits per IEC 60947-1. Fire resistance is 960 °C on parts supporting live components, 650 °C on other parts per IEC 60695-2-12. Protective treatment is TH per IEC 60068 (tropical heat and humidity). Operating altitude is 2000 m without derating.

Frequently asked questions

Where can I buy LUCL32ES?

The LUCL32ES is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest alternative to LUCL32ES in the TeSys Ultra family?

Within the TeSys Ultra range, the LUCL32ES is the specific variant for 48 V AC / 48-72 V DC control voltage. Other LUCL variants differ by control voltage and coil characteristics — the mechanical footprint and protection function are identical across the family, so a different control-voltage variant is the only alternative if the supply voltage changes.

What compliance documentation does Schneider provide for LUCL32ES?

The LUCL32ES is certified to EN/IEC 60947-6-2, UL 60947-4-1 with phase barrier, and CSA C22.2 No 60947-4-1 with phase barrier. It also meets IEC 60068 TH protective treatment for tropical environments.
