11B180L0048C48 - 3P CONTACTOR 48VAC C/W LATCH 48VDC

Why Choose the 11B180L0048C48?

Designed for demanding industrial control, the Lovato B180 three-pole contactor (SKU 11B180L0048C48) pairs a 48VAC/DC coil with an integrated mechanical latch for secure maintained switching. With AC-3 Ie 185 A, it handles heavy motor loads confidently. Rated Ui 1000 V and Uimp 8 kV, it withstands harsh electrical environments, while screw mounting and reliable terminals support straightforward panel installation across machinery, power distribution and automation assemblies.

Engineered for longevity, it offers Ith 275 A, mechanical life of 10,000,000 cycles, and operation from -50 to 70 °C at altitudes up to 3000 m (pollution degree 3). Conforming to IEC/EN 60947-1 and 60947-4-1, plus UL 60947-1/-4-1 and CSA C22.2 No. 60947-1/-4-1, it suits globally aligned projects. Supplied with mechanical latch (G495) pre-fitted, it helps simplify build and supports consistent performance in demanding duty cycles.
