Product FAQs
6 answersWhat does the "C" in the CFD63B110L catalog number indicate?
The "C" designates this as a current-limiting circuit breaker. It features a fuseless, current-limiting architecture designed to safely interrupt high-level short circuits up to 200kA at 480V.
What wire sizes are compatible with the lugs on the CFD63B110L?
The factory-installed lugs accept 6 AWG to 350 kcmil copper (Cu) wire, or 4 AWG to 350 kcmil aluminum (Al) wire.
Is the trip unit on the CFD63B110L adjustable?
Yes, this thermal-magnetic breaker features a fixed thermal trip for overload protection and an adjustable magnetic trip for short-circuit protection. This allows installers to fine-tune the instantaneous trip settings for better system coordination.
What types of equipment is the CFD63B110L designed to fit?
This FD-frame breaker is designed for use in Siemens Sentron panelboards, switchboards, and enclosures.
What does the "L" at the end of the CFD63B110L part number mean?
The "L" indicates that the breaker is supplied with factory-installed line and load side lugs.
Does the CFD63B110L require external fuses to achieve its 200kAIC rating at 480V?
No, the CFD6 series utilizes a fuseless current-limiting design to achieve its high interrupting ratings without the need for upstream fuses.
