1321-3RA45-B

The Allen-Bradley 1321-3RA45-B line reactor is a 3-phase line reactor that can be used at both the input and output sides of equipment, including AC drives and motors. It belongs to the 1321 power conditioning equipment product line from Allen-Bradley. The rated inductance and fundamental current levels for the 1321-3RA45-B line reactor are 0.7 Millihenry and 45 Amps, respectively. The inductor is enclosed inside an IP 11 rated enclosure which is made of sheet steel which complies with the NEMA/UL specifications. For termination, 85 Amps rated terminal blocks are supplied with the 1321-3RA45-B line reactor. Allen-Bradley recommends 20 pounds on an inch of peak torque and 4 18 AWG as the maximum/minimum wire sizes. The 1321-3RA45-B line reactor complies with the CE, UL 508, and SCA C22.2 Class N200C standards.

The 1321 series line reactors are available with 1.5%, 3%, and 5% impedance ratings based on the fundamental current ratings. The DV/DT protection on the line reactors complies with the NEMA MG-1 part 31. The overload ratings for 1321-3RA45-B line reactors are 300% of the fundamental current for a time duration of 30 minutes and 200% of the fundamental current for a time duration of 1 minute. The electrical specifications for the 1321-3RA45-B line reactor include 690 Volts AC peak rated voltage, 20-kilohertz peak switching frequency, a 135 degrees Celsius temperature rise, and 3000 Volts RMS dielectric strength. The environmental specifications include 3280 feet peak altitude and 40 degrees Celsius peak ambient temperature. The typical inductance curve is 100% at a 100% current rating, 150% at a 150% current rating, and 50% at a 350% current rating. The Allen-Bradley 1321 series line reactors provide compensation against high frequencies and other currents caused by harmonics.
