Product FAQs
8 answersWhat panels and enclosures are compatible with the CFD63B150?
This breaker is designed for use in Siemens Sentron panelboards, including P1, P2, and P3 models, as well as compatible switchboards, motor control centers, and standalone enclosures.
What wire sizes are accepted by the standard lugs on this breaker?
The standard TA1FD350A lugs accept 6 AWG to 350 kcmil copper wire, or 4 AWG to 350 kcmil aluminum wire.
What is the adjustable magnetic trip range for the CFD63B150?
The instantaneous magnetic trip on this 150A breaker can be adjusted between 800A and 1500A to coordinate with downstream devices and handle specific inrush currents.
What is the difference between the CFD63B150 and the FD63B150 or HFD63B150?
The CFD63B150 is the fuseless current-limiting version with an ultra-high interrupting capacity of 200kA at 480V. The standard FD63B150 is rated for 35kA at 480V, and the HFD63B150 is rated for 65kA at 480V.
Can the CFD63B150 be reverse fed?
Yes, CFD6 frame circuit breakers are UL listed for reverse feed applications, allowing line power to be connected to either the top or bottom terminals.
Is the trip unit on the CFD63B150 interchangeable?
No, CFD6 frame breakers feature a factory-sealed, non-interchangeable thermal-magnetic trip unit. Removing the sealed cover voids the UL listing.
Does this breaker provide current-limiting protection without fuses?
Yes, the CFD63B150 is a fuseless current-limiting circuit breaker. It uses a specialized contact design to limit let-through current during high-level faults without requiring external fuses.
How does this breaker mount into a panel?
The CFD63B150 is a unit-mount, bolt-on circuit breaker. It secures directly to the panel bus or mounting pan using bolted connections rather than a plug-in mechanism.
