Block Contactor AF1250-30-11-70
The AF1250-30-11-70 is a 3 pole contactor designed for 1000 V IEC or 600 V UL applications, with pre-mounted auxiliary contacts and Main Circuit Bars. It switches power circuits up to 1260 A (AC-1) or 1210 A for UL general use. Thanks to AF technology, it supports 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 even in unstable networks. Surge protection is built-in, offering a compact solution.
The AF contactors feature a block type design and can be easily extended with add-on auxiliary contact blocks and a wide range of accessories.
