Product FAQs
6 answersWhat panelboards and enclosures are compatible with the FXD63B225 breaker?
This unit-mount FD-frame breaker is designed for Siemens Sentron series panelboards (P1, P2, and P3), switchboards, motor control centers (MCCs), and standalone enclosures designed for FD-frame components.
What type of mounting does the FXD63B225 utilize?
It features a bolt-on connection for unit mounting. Ensure torque specifications listed on the breaker face are followed when connecting the lugs to the bus or conductors.
How do I adjust the trip settings on the FXD63B225?
The FXD63B225 features a thermal-magnetic trip unit with a fixed thermal element (long-time) at 225A and an adjustable magnetic element (instantaneous). The magnetic trip can be adjusted via the dial on the face of the breaker to coordinate with downstream devices and handle specific motor inrush currents.
Can the FXD63B225 be used in DC electrical systems?
Yes, this breaker is rated for both AC and DC systems. It offers a DC interrupting capacity of 30kA at 250VDC and 18kA at 500VDC. Ensure proper series wiring of poles when installing in 500VDC applications.
What is the difference between the FXD63B225 and the HFXD63B225?
Both are 225A, 3-pole, FD-frame breakers. The difference lies in their maximum interrupting capacity. The FXD63B225 is rated for 35kA at 480VAC, whereas the HFXD63B225 is the high-interrupting version rated for 65kA at 480VAC.
What safety functions are provided by the FXD63B225 trip unit?
The LI (Long-Time, Instantaneous) thermal-magnetic trip unit provides foundational circuit protection. The fixed thermal element protects against sustained overloads, while the adjustable magnetic element clears sudden short circuits to protect wiring and electrical equipment.
