11B400L00110110 - 3P CONTACTOR 110/125V C/W LATCH 110VAC
MPN: 11B400L00110110
Alt. SKU: B400L00110110
Why Choose the 11B400L00110110?
Engineered for heavy-duty motor control, the Lovato B400 three-pole contactor (SKU 11B400L00110110) combines a 110-125V AC/DC coil with a factory-fitted mechanical latch for secure hold-in. Delivering IEC AC3 Ie 420A at 400V and AC1 Ith 550A, it handles demanding switching with confidence. Screw mounting and robust construction make installation straightforward across industrial panels and switchgear.
Inbuilt durability includes Ui 1000V, Uimp 8kV, and a mechanical life rated to 10,000,000 cycles, with operation from -50 to +70 °C and use up to 3000 m (pollution degree 3). Conformity to IEC/EN 60947-1/-4-1, UL and CSA standards underpins reliability, while the integrated latch (G495) and 350 HP at 480V (UL/CSA) broaden application flexibility.
