Description
AF370-40-11-13 Block Contactor by ABB
The AF370-40-11-13 is a 4 pole contactor designed for 1000 V IEC or 600 V UL applications. It features pre-mounted auxiliary contacts and Main Circuit Bars, capable of controlling motors up to 200 kW at 400 V AC (AC-3) and switching power circuits up to 525 A (AC-1) or 420 A for UL general use. Thanks to AF technology, it offers a wide control voltage range of 100-250 V at 50/60 Hz and DC, effectively managing large control voltage variations, reducing panel energy consumption, and ensuring distinct operations in unstable networks. Surge protection is integrated, providing a compact, reliable solution.
The contactor has a block type design and is easily extendable with add-on auxiliary contact blocks and a wide range of accessories. It includes a mounting kit with all necessary screws, washers, sockets for terminal connections, and mounting screws.
