11B5000048 - 3P CONTACTOR B500.00 48VAC/DC

Why Choose the 11B5000048?

Lovato’s B500 three-pole contactor with 48 VAC/DC coil delivers robust switching for demanding motor and power circuits. Rated AC-3 Ie 520 A at 400 V and Ith 700 A, it combines high performance with compact reliability. With Ui 1000 V and Uimp 8 kV, it offers strong insulation and impulse withstand, while screw mounting and 35 Nm terminal torque support secure, serviceable installation in industrial panels.

Engineered for endurance, the B500 achieves 5,000,000 mechanical cycles and operates from -50 to 70 °C, with storage from -60 to 80 °C. Rated for installations up to 3000 m and pollution degree 3, it suits harsh environments. Conformity to IEC/EN 60947 and UL/CSA standards underpins global compliance, while a 1,798 g build and sustainability certification support reliable, responsible panel integration.
