Why Choose the NF31E-11 [1SBH137001R1131]
The NF31E-11 is a 4-pole contactor relay rated for 690 V IEC or 600 V UL applications, featuring screw terminals for secure connections. Designed for switching auxiliary and control circuits, it utilises AF technology to support a broad control voltage range (24-60 V AC at 50/60 Hz and 20-60 V DC), accommodating significant voltage fluctuations while minimising panel energy consumption and ensuring reliable operation in unstable power environments. Integrated surge protection enhances durability within a compact form factor. The block-type design allows straightforward expansion with add-on auxiliary contact blocks and a comprehensive selection of compatible accessories. Mechanically-linked auxiliary contacts conform to Annex L of IEC 60947-5-1 and are clearly identified with the standard "Mechanically Linked" marking on the side.
