Part of the Series C family, the Eaton HFD2150 is a 2-pole, 150A molded case circuit breaker built for commercial and industrial power distribution. This F-frame device provides reliable thermal-magnetic protection. It bolts securely into Eaton Pow-R-Line panelboards, switchboards, and motor control centers. For facility upgrades, this unit is replaced by the PDG22M0150TFFJ. Rated at 65 kAIC at 480VAC, this current-limiting breaker handles high fault currents and is HACR rated.

Product FAQs
8 answers
What panelboards are compatible with the HFD2150?
This F-frame breaker is designed for use in Eaton Series C panelboards, Pow-R-Line panelboards, switchboards, and motor control centers. It requires a bolt-on connection directly to the busbar.
What wire sizes are accepted by the standard lugs on this breaker?
The included lugs accept 4 AWG through 4/0 AWG copper or aluminum conductors. Always verify the required torque specifications printed on the breaker faceplate during installation to ensure a secure connection.
What does the H in the HFD2150 catalog number signify?
The H indicates that this is the high-interrupting capacity version of the standard FD frame. It provides a 65kAIC rating at 480VAC, whereas the standard FD frame offers a lower 35kAIC rating.
Is the trip unit on the HFD2150 adjustable in the field?
No, this breaker features a fixed thermal and fixed magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory set and cannot be modified by the user.
Can this molded case circuit breaker be used in DC applications?
Yes, the HFD2150 is rated for up to 250VDC with an interrupting capacity of 22kAIC, making it suitable for specific direct current industrial control and distribution systems.
What is the difference between the FD2150 and the HFD2150?
The primary difference is the short-circuit interrupting capacity. The HFD2150 is the high-interrupting version rated at 65kAIC at 480VAC, while the standard FD2150 is rated at 35kAIC. They share the exact same physical dimensions and mounting footprint.
Can the HFD2150 replace an older FDB2150 breaker?
Yes, the HFD2150 shares the same Series C F-frame footprint as the FDB2150. Upgrading to the HFD provides significantly higher interrupting ratings while maintaining physical compatibility with your existing panelboard.
How does the thermal-magnetic trip unit function on this breaker?
The thermal element provides delayed protection against sustained overloads, allowing for temporary inrush currents without nuisance tripping. The magnetic element offers instantaneous protection, tripping the breaker immediately in the event of a severe short circuit.
