Product FAQs
5 answersAre terminal lugs included with the PXD63B140 breaker?
No, this breaker is typically supplied without lugs. You must purchase compatible lug kits separately, such as the TA5P600, which accepts five 300 to 600 kcmil aluminum or copper conductors per phase.
What equipment is the PXD63B140 designed to fit?
This PD frame breaker is engineered for installation in Siemens switchboards and motor control centers. It is commonly used for heavy industrial and commercial power distribution.
How is the trip unit configured on the PXD63B140?
It features a thermal magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short circuit protection.
Can the PXD63B140 replace older Siemens or ITE PD frame breakers?
Yes, it shares the standard PD frame dimensions of 16 inches high, 9 inches wide, and 6.19 inches deep. It can serve as a direct replacement for legacy PD63B140 breakers in existing equipment.
Does the PXD63B140 feature an interchangeable trip unit?
No, the PXD63B140 comes factory assembled with a non-interchangeable trip unit. If your application requires an interchangeable trip design, you will need to source the standard PD6 frame and trip unit components separately.
