Part of the Sentron series, the Siemens FD63B200 is a 3-pole, 200A molded case circuit breaker designed for commercial and industrial power distribution. It provides reliable long-time and instantaneous (LI) protection. This unit mount MCCB installs into Siemens P1 subfeed, P2, P3, P4, and P5 panelboards, as well as switchboards and motor control centers. Rated 35kAIC at 480VAC, this FD frame breaker features an interchangeable thermal-magnetic trip unit and is HACR rated.
Which panelboards and switchboards are compatible with the FD63B200 breaker?
This unit-mount breaker is compatible with Siemens P1 (when used as a subfeed), P2, P3, P4, and P5 panelboards. It is also suitable for installation in Siemens switchboards and motor control centers.
What wire sizes are accepted by the standard lugs on the FD63B200?
The standard terminal lugs accommodate 6 AWG to 350 kcmil copper (Cu) conductors, or 4 AWG to 350 kcmil aluminum (Al) conductors.
What is the proper mounting configuration for this breaker?
The FD63B200 requires a bolt-on connection. It is a unit-mount breaker, meaning it fastens securely to the panelboard chassis or mounting pan rather than using a plug-in or snap-on connection.
What is the difference between the Siemens FD63B200 and FXD63B200?
The FD63B200 features an interchangeable trip unit, allowing the trip mechanism to be replaced or upgraded without removing the breaker frame. The FXD63B200 is functionally identical but features a factory-sealed, non-interchangeable trip unit.
Are the frame and trip unit available separately for the FD63B200?
Yes. Because the FD63B200 uses an interchangeable design, the 250A maximum FD63F250 frame and the 200A FD63T200 trip unit can be sourced as individual components. The FD63B200 catalog number represents the complete, fully assembled breaker.
Is this circuit breaker rated for direct current (DC) systems?
Yes, the FD63B200 is approved for DC applications up to 500VDC, where it provides an 18kA interrupting rating. When installing in DC applications, verify the proper series pole wiring configuration as outlined by Siemens.
Does the FD63B200 include GFCI or AFCI protection?
No. This is a standard thermal-magnetic circuit breaker designed to provide long-time and instantaneous trip protection against overloads and short circuits. It does not feature ground fault or arc fault sensing capabilities.
