Product FAQs
8 answersWhat switchboards are compatible with the RXD63B200 circuit breaker?
This unit-mount breaker is designed for installation in Siemens SB1, SB2, and SB3 switchboards. It requires adequate physical space for an R-frame footprint.
How does the adjustable magnetic trip setting benefit panel coordination?
The adjustable instantaneous magnetic trip allows electricians to fine-tune the short-circuit response. This helps ensure that downstream faults trip the closest breaker rather than the main 2000A breaker, improving overall system reliability.
Is the RXD63B200 suitable for direct current applications?
Yes. In addition to its AC ratings, this breaker is rated for 30kAIC at 250VDC and 25kAIC at 500VDC, making it suitable for heavy industrial DC systems.
Are terminal lugs included with this 2000A breaker?
Due to the large conductor requirements for 2000A service, terminal lugs are often configured based on specific project needs. You must verify your wire size, material, and number of conductors per phase to select the correct mechanical or compression lug kits.
Can this Siemens breaker replace legacy ITE R-frame breakers?
Yes. Siemens manufactures this RD frame breaker, which serves as a direct replacement for many older ITE R-frame breakers with matching specifications. Always verify physical dimensions and busbar configurations before retrofitting.
What does a unit-mount configuration mean for installation?
A unit-mount, or bolt-on, configuration means the breaker is bolted directly to the mounting pan or busbars using hardware. It is not designed for plug-in or draw-out chassis systems.
Can internal accessories be added to the RXD63B200?
Yes, Siemens R-frame circuit breakers support various field-installable internal accessories. These include shunt trips, auxiliary switches, and undervoltage releases, which are used for remote tripping and status signaling.
What are the recommended safety checks before energizing this breaker?
Before energizing, verify that all bolt-on connections and terminal lugs are torqued to the manufacturer specifications. Ensure the adjustable magnetic trip is set correctly for the connected load and coordination study.
