Product FAQs
6 answersWhat is the adjustable magnetic trip range for the FD63B175?
The instantaneous magnetic trip setting on this breaker is adjustable between 900A and 2000A.
Which replacement lug kit is compatible with this breaker?
The standard replacement line and load lug kit for the FD6 frame is the Siemens TA1FD350A. A complete FD63B175 assembly typically includes these lugs.
What are the individual component part numbers for this assembled breaker?
The FD63B175 is a complete assembly that consists of the 250A rated FD63F250 frame, the 175A rated FD63T175 interchangeable trip unit, and TA1FD350A lugs.
What is the difference between the FD63B175 and FXD63B175?
The FD63B175 includes an interchangeable trip unit, which allows the trip mechanism to be removed or replaced without changing the breaker frame. The FXD63B175 has a fixed, non-interchangeable trip unit. Both breakers share the same physical footprint and panel compatibility.
Can I use the FD63B175 to replace an obsolete ITE breaker?
Yes. Siemens acquired ITE, and current Sentron FD6 series breakers serve as direct drop-in replacements for legacy ITE and Gould F-frame circuit breakers with matching specifications.
How do you adjust the instantaneous trip point on the FD6 trip unit?
The instantaneous magnetic trip adjustment is made through the front cover of the breaker. Simply depress the indicating knob on the trip unit and rotate it to the desired trip position.
