Product FAQs
7 answersWhat does the 'V' suffix indicate on the HFD3050V catalog number?
The 'V' suffix means the thermal-magnetic trip unit is calibrated for a 50 degrees Celsius (122 degrees Fahrenheit) ambient temperature. Standard Series C breakers are calibrated for 40 degrees Celsius. This makes the HFD3050V suitable for high-temperature environments like generator housings or specific industrial enclosures.
Can the HFD3050V be used to replace a standard HFD3050 or FD3050 breaker?
Yes. It shares the exact same F-frame physical dimensions, mounting footprint, and bolt-on configuration as the standard HFD3050 and older FD3050 breakers. The primary difference is the 50 degrees Celsius thermal calibration, which is fully compatible with standard applications.
What type of trip unit is installed in the HFD3050V?
This breaker features a non-interchangeable, fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection and does not have adjustable dials for trip settings.
What wire sizes are compatible with the standard lugs on this breaker?
The factory-installed lugs accept 14 AWG through 1/0 AWG copper or aluminum conductors. Ensure all connections are torqued to the manufacturer specifications printed on the breaker label during installation.
Is this breaker compatible with direct current (DC) systems?
Yes, the HFD3050V is rated for up to 250VDC with a 22kA interrupting capacity. This allows it to be used in specific DC control panels, battery systems, or distribution applications.
How does the HFD3050V mount inside an enclosure?
This is a panel-mount, bolt-on circuit breaker. It bolts directly to the bus or chassis of compatible Eaton Series C panelboards, switchboards, and motor control centers. It is not designed for DIN rail installation.
Can I add internal accessories like a shunt trip to the HFD3050V?
Yes, Eaton Series C F-frame breakers support field-installable internal accessories. You can install shunt trips, auxiliary switches, or undervoltage releases under the front accessory cover.
