Why Choose the NF31E-12 [1SBH137001R1231]
The NF31E-12 is a 4-pole contactor relay rated for 690 V IEC or 600 V UL applications, featuring screw terminals for secure wiring. Designed for switching auxiliary and control circuits, it utilises AF technology to accommodate a broad control voltage range (48-130 V AC/DC, 50/60 Hz), enabling reliable operation despite significant voltage fluctuations and reducing panel energy consumption. Integrated surge protection enhances durability within compact dimensions. 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" marking on the side.
