ABB NF44E minicontactor, 4NO+4NC, bobina electrónica 24-60V AC/20-60V DC, conexiones por tornillo, carril DIN

Forget stocking separate AC and DC coil versions—the ABB NF44E auxiliary contactor handles both with a single wide-range electronic coil that accepts 24–60 V AC (50/60 Hz) and 20–60 V DC. This 8-pole unit (4 normally open + 4 normally closed) delivers the auxiliary contacts you need for interlocking, signaling, and control logic in a compact, DIN-rail-mountable package.

Highlights

• Wide-range electronic coil: 24–60 V AC (50/60 Hz) and 20–60 V DC
• 4 normally open + 4 normally closed auxiliary contacts
• Compact design for DIN rail or screw mounting
• High electrical durability: 5 million operations
• Mechanical durability: 10 million operations
• Rated insulation voltage 690 V, impulse withstand 6 kV
• Operating temperature range: -40 °C to +70 °C
• Degree of protection IP20
• Complies with IEC 60947-5-1, UL, CSA

In daily use

Installation is straightforward thanks to screw terminals that accept a wide range of conductor sizes. The contactor's electronic coil draws only 3.5 W during both pull-in and holding, reducing panel heat and energy consumption. Its wide voltage tolerance makes it ideal for installations with fluctuating control voltages, and the 4NO+4NC configuration provides ample auxiliary contacts for interlocking, signaling, and control logic without adding extra relays.
