Why Choose the NF31E-14 [1SBH137001R1431]
The NF31E-14 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 (250-500 V AC 50/60 Hz and DC), accommodating significant voltage fluctuations while minimising panel energy consumption and maintaining reliable operation in unstable power networks. Integrated surge protection enhances durability within a compact form factor. The block-type design allows for straightforward expansion with add-on auxiliary contact blocks and a comprehensive range of compatible accessories. Mechanically linked auxiliary contacts meet Annex L requirements of IEC 60947-5-1 and are clearly identified with the standard "Mechanically Linked" side marking for easy verification.
