Product FAQs

What does the S06 suffix mean on the FD3150S06 circuit breaker?
The S06 suffix indicates that this breaker comes with a factory-installed shunt trip. The shunt trip operates at 48 to 127 VAC or 48 to 60 VDC and is typically mounted in the left pole.
Can I use the FD3150S06 to replace a standard FD3150?
Yes, it shares the same physical dimensions and mounting as a standard FD3150, but it includes a factory-installed shunt trip. If your application does not require a shunt trip, you can leave the accessory leads disconnected or opt for the standard FD3150.
Where are the shunt trip leads located on the FD3150S06?
The factory-installed shunt trip is mounted in the left pole of the breaker, with the pigtail leads exiting the breaker for connection to your control circuit.
Does the FD3150S06 come with both line and load lugs?
Standard Eaton F-frame breakers like the FD3150S06 include load-side lugs only, which accept 4 AWG to 4/0 AWG copper or aluminum wire. The line side is designed to bolt directly to the busbar. If your installation requires line-side wire connections, you will need to install a separate line lug kit.
Are the trip settings adjustable on the FD3150S06?
No, this breaker features a fixed thermal and fixed magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are non-adjustable.
Which panelboards and enclosures are compatible with the FD3150S06?
This F-frame breaker is designed for use in Eaton Series C panelboards, motor control centers, and switchboards.
What safety precautions should be taken before wiring the shunt trip on the FD3150S06?
Always verify that the control circuit power is completely de-energized before connecting the shunt trip leads. Ensure the control voltage matches the 48 to 127 VAC or 48 to 60 VDC rating of the S06 accessory to prevent coil burnout or failure to trip.
Can the FD3150S06 be used in reverse feed applications?
Yes, Eaton Series C F-frame thermal-magnetic circuit breakers are suitable for reverse feed applications.
Is the FD3150S06 rated for DC applications?
Yes, it is rated for up to 250VDC with an interrupting capacity of 10kAIC. Note that in DC applications, the magnetic trip levels are approximately 40 percent higher than in AC applications.

175amp molded case circuit breaker
The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.
Next day shipping came quickly even though the 4th of July was coming.
I wish it came with new installations hardware but that isn’t a deal breaker.
