Product FAQs
7 answersWhich panelboards and enclosures are compatible with the CFD63B100L?
This unit mounts directly into Siemens Sentron P1, P2, and P3 panelboards, as well as compatible switchboards, motor control centers, and standalone enclosures designed for FD frame breakers.
What wire sizes are accepted by the line and load lugs on the CFD63B100L?
The included line and load lugs accept 6 AWG to 350 kcmil copper (Cu) wire, or 4 AWG to 350 kcmil aluminum (Al) wire.
How is the trip unit configured on the CFD63B100L?
This breaker features a thermal-magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal element for long-time protection is fixed, while the magnetic instantaneous trip is adjustable to coordinate with downstream loads.
Is the CFD63B100L suitable for high fault current applications?
Yes, this breaker is designed for high-capacity systems, offering a maximum interrupting rating of 200kA at 480V AC and 100kA at 600V AC. The CFD6 series features a fuseless, current-limiting design to safely clear severe faults.
How is the CFD63B100L installed into a system?
This is a unit mount circuit breaker, meaning it bolts directly to the mounting surface or enclosure backpan rather than plugging into a busbar.
What safety standards does the CFD63B100L meet?
This breaker meets UL 489 and IEC 60947-2 standards for molded case circuit breakers, ensuring reliable protection for commercial and industrial electrical systems.
What does the CFD6 prefix indicate compared to standard FD frame breakers?
The CFD6 prefix designates this as the current-limiting version of the Siemens FD frame. It provides a much higher interrupting capacity (up to 200kA at 480V) than standard FD6 or HFD6 breakers while maintaining the same physical footprint.
