Why Choose the NF31E-13 [1SBH137001R1331]
The NF31E-13 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 wide control voltage range (100–250 V AC 50/60 Hz and DC), accommodating significant voltage fluctuations while minimising panel energy consumption and ensuring reliable operation in unstable power networks. Integrated surge protection enhances durability within a compact footprint. The block-type design allows straightforward expansion with add-on auxiliary contact blocks and a comprehensive range of compatible accessories. Mechanically linked auxiliary contacts conform to Annex L of IEC 60947-5-1 and are clearly identified by the standard "Mechanically Linked" side marking.
