Description
Engineered for commercial environments, this 15A F-Frame breaker utilizes thermal-magnetic technology for reliable LI protection. The Phase C connection helps maintain balanced loads. This component mounts into standard Square D I-Line panelboards. Facilities transitioning to current hardware can use the PowerPact BGA140153 as a substitute. With a high interrupting capacity of 65kA at 240V, it safely clears severe faults. The HACR rating makes it suitable for heating and cooling equipment.Specifications

Product FAQs
8 answersCan I install the FH16015C in a standard Square D QO or NQ load center?
No. The FH16015C features an I-Line plug-on connection. It is exclusively designed for Square D I-Line panelboards and switchboards, and will not fit in standard residential or commercial QO, NQ, or NF load centers.
What does the "C" at the end of the FH16015C catalog number indicate?
The "C" suffix indicates that this 1-pole breaker is factory-configured for a Phase C connection on the I-Line bus. If you need to connect to Phase A or Phase B, you must order the corresponding FH16015A or FH16015B model, as the phase connection cannot be changed in the field.
What is the recommended lug torque for the FH16015C circuit breaker?
The load-side mechanical lug on the 15A FH-frame breaker should be torqued to 35 lb-in for 14-4 AWG copper or aluminum wire. Always verify with the manufacturer label on the breaker before finalizing the installation.
How does the line-side connection work on the FH16015C?
The FH16015C utilizes Square D's proprietary I-Line plug-on design. The line side features blow-on jaw connectors that push directly onto the panelboard's bus assembly, while a retaining screw secures the breaker in place. The load side uses a standard mechanical lug.
What is the difference between the Square D FH16015C and the FA16015C?
Both are 1-pole, 15-amp F-frame circuit breakers with I-Line mounting. The difference lies in the interrupting capacity. The FH series is the high-interrupting version, designed to safely clear higher fault currents than the standard FA series.
What is the modern replacement for the obsolete FH16015C?
The FH16015C is part of the legacy Square D F-frame series, which has been replaced by the PowerPact B-frame series. A direct modern equivalent for a 1-pole, 15A I-Line breaker with a Phase C connection is a PowerPact B-frame model, such as the BGA140153, depending on your required interrupting rating.
What type of protection does the "LI" trip function provide on the FH16015C?
The "LI" designation indicates a thermal-magnetic trip unit providing two types of protection. The Long-Time (L) thermal element protects against sustained overloads, while the Instantaneous (I) magnetic element trips immediately in the event of a short circuit. Both settings are fixed on this model.
Can I field-install electrical accessories like a shunt trip or auxiliary switch on the FH16015C?
No. Legacy Square D F-frame circuit breakers, including the FH16015C, do not accept field-installed internal electrical accessories. Any required accessories, such as shunt trips or auxiliary contacts, must be factory-installed.
