ABB 1SBH137001R1140 NF40E-11 auxiliary contactor 24-60V 50/60Hz / 20-60V DC

The 4-pole NF auxiliary contactors are used for switching auxiliary and control circuits. They have an electronic coil interface which allows a large control voltage range and can cope with large control voltage fluctuations. NF auxiliary contactors have a built-in overvoltage protection and do not need any additional extinguishing elements. The types with the coil code -11 are unsuitable for connection to 24WDC SPS outputs.
