Eaton HFD2045N Circuit Breaker

The Eaton HFD2045N, also listed as Cutler-Hammer HFD2045N, is a two-pole circuit breaker rated for 45 amperes at a maximum of 600 volts, designed to protect 2-pole circuits by opening the circuit on both poles when an overcurrent or fault is detected. This device is part of Eaton's Cutler-Hammer protection line and is intended for use in standard electrical panels found in commercial and industrial environments where 600V service is common. With a 2P configuration and a 45A rating, the HFD2045N identifies its role as the protective device for multi-conductor feeders in higher-voltage distributions, providing overcurrent protection for circuits and helping to isolate faults on each pole. Use of this model ensures compatibility with Eaton/Cutler-Hammer breaker families and its 600V rating delineates the maximum system voltage it is intended to interrupt, making it a precise choice for installations requiring a 45A, 600V, two-pole protection solution.
