11B250L00110110 - 3P CONTACTOR 110/125V C/W LATCH 110VAC
MPN: 11B250L00110110
Alt. SKU: B250L00110110
Why Choose the 11B250L00110110?
Lovato B250 three-pole contactor with AC/DC coil and mechanical latch (G495) delivers dependable motor switching for heavy-duty applications. Rated Ie (AC-3) 265 A and Ith 350 A, it suits demanding AC-3 duty. The 110–125 VAC/DC coil and integrated latch simplify control schemes where maintained contact is required. Screw mounting and 35 Nm terminal tightening torque provide secure installation in panels.
Engineered for longevity, the B250 offers 10,000,000 mechanical cycles, Ui 1000 V and 8 kV impulse withstand for insulation robustness. It operates from −50 to +70°C (storage −60 to +80°C) and up to 3000 m altitude, pollution degree 3. Weighing 1028 g, it conforms to IEC/EN 60947-1 and 60947-4-1, UL and CSA equivalents, supporting global compliance and sustainability objectives.
