Block Contactor AF305-30-11-13
The AF305-30-11-13 is a 3 pole contactor rated for 1000 V IEC or 600 V UL applications. It features pre-mounted auxiliary contacts and Main Circuit Bars, suitable for controlling motors up to 160 kW at 400 V AC (AC-3) or 250 hp at 480 V UL and switching power circuits up to 500 A AC-1 or 400 A UL general use. The contactor utilizes AF technology, providing a wide control voltage range from 100 to 250 V at 50/60 Hz and DC, managing large control voltage variations effectively, which reduces panel energy consumption and guarantees reliable operation even in unstable networks.
It includes built-in surge protection for compactness and safety. The block type design allows easy expansion with add-on auxiliary contact blocks and a broad range of accessories. A mounting kit is included with all necessary screws, washers, sockets for terminal connections, and device mounting screws.
