11B1454L00220220 - 4P CONTACTOR 220/240V C/W LATCH 220VAC

Why Choose the 11B1454L00220220?

Designed for demanding industrial switching, the Lovato B145 four-pole contactor (SKU 11B1454L00220220) combines a 220...240 V AC/DC coil with a pre-fitted mechanical latch (G495) for secure maintained operation. With Ith (AC-1) 250 A, Ui 1000 V and Uimp 8 kV, it provides robust performance. Screw mounting and high-integrity terminals support reliable installation in control panels and power distribution assemblies.

Built for longevity, this contactor achieves up to 10,000,000 mechanical cycles and operates from -50 to +70 °C, with storage -60 to +80 °C. Rated for use up to 3000 m and pollution degree 3, it conforms to IEC/EN 60947-1 and 60947-4-1, plus UL and CSA standards. Ideal for heavy-duty AC-1 power switching where dependable latching and 220...240 V control are required.
