11B2500048 - 3P CONTACTOR B250.00 48V

Why Choose the 11B2500048?

Lovato B250 contactor (SKU 11B2500048) is a three-pole contactor with a 48VAC/DC coil, delivering IEC AC-3 Ie of 265 A. Built for demanding three-phase motor control, it combines robust screw mounting with a rated insulation voltage of 1000 V and 8 kV impulse withstand. With an Ith of 350 A and a mechanical life of 10,000,000 cycles, it offers dependable switching in industrial panels.

Engineered to perform from -50 to 70°C and up to 3000 m altitude, this B250 contactor endures harsh conditions (pollution degree 3) while maintaining reliable operation. Terminal tightening torque of 35 Nm secures conductors, and the 9550 g construction underscores durability. Conformity with IEC/EN 60947-1/-4-1, UL and CSA standards supports acceptance across projects requiring proven safety and performance.
