The 1321-3R55-A from Allen Bradley belongs to the 1321 Power Products series, and it is a three-phase line reactor aimed at improving electrical performance. Rated for a maximum current of 55 A, this unit functions with a nominal inductance of 0.5 mH. Designed for operating in systems with rated voltage levels of 600 VAC, this reactor is tailored for compatibility with standard industrial applications.

This reactor operates effectively within a frequency spectrum from 50 Hz to 60 Hz, providing versatility in different setups. The open-type enclosure construction of the 1321-3R55-A poses minimal hindrance for internal maintenance and adjustments. In addition to its accommodating design, this reactor has an IP00 rating, which indicates it is primarily intended for indoor conditions and lacks protective housing from environmental hazards.

Power losses during operation are limited to 64 W, maintaining efficiency in operation while preventing overheating. Additionally, the reactor’s terminal torque specifications are determined at 5.09 Nm, capable of securing wire sizes ranging from 10 mm² up to 50 mm². These features culminate to make the 1321-3R55-A a practical choice for enhancing power quality in three-phase systems.
