It plugs into the front face of a TeSys Ultra base (LUCC-compatible frame) and handles motors rated up to 4 kW at 400...440 V AC single-phase. Beyond basic overload, it includes earth fault protection, phase failure and imbalance protection, and short-circuit monitoring — functions that make it a central protective element in a motor starter assembly. Coil holds at 24 V DC; typical sealed draw is 80 mA, with a 220 mA inrush during closing. The control circuit dissipates 3 W with either the LUB32 or LUB38 remote control circuit. The LUCC18BL is rated for utilisation categories AC-41, AC-43, and AC-44 covering resistive, moderate-inductive, and motor-starting loads. Its thermal overload class 10 trip curve suits single-phase motor protection. Rated insulation voltage is 690 V per IEC 60947-6-2, 600 V per UL and CSA — comfortably above the 400 V supply this unit is typically paired with for the 4 kW rating. IP20 on the front and wired terminals, IP40 front panel outside connection zone — it’s a panel-internal device, not for wet environments. Manual reset means it locks out on fault and requires a physical push to restore; good for applications where automatic restart is undesirable. Certified to IEC 60947-6-2, UL 60947-4-1, and CSA C22.2 No 60947-4-1 (all with phase barrier). That covers most global panel requirements. Safe separation of circuits is rated at 400 V SELV between control/auxiliary and main circuits. Fire resistance: live-part supports withstand 960 °C (IEC 60695-2-12), other parts 650 °C. Shock resistance: 10 gn with power poles open, 15 gn closed — robust for transport and vibration in typical industrial panels.","metaTitle":"Schneider LUCC18BL TeSys Ultra Control Unit, 24VDC, Manual R","metaDescription":"Schneider Electric LUCC18BL TeSys Ultra advanced control unit. 24 VDC coil, manual reset, class 10 overload, 4 kW single-phase motor protection.
