Product FAQs
7 answersWhat types of enclosures or panels are compatible with the PXD63B160?
This bolt-on molded case circuit breaker is designed specifically for use with Siemens switchboards and motor control centers.
Is the PXD63B160 suitable for reverse-fed applications?
Yes, this breaker is suitable for reverse-fed applications, allowing power to be supplied to either the line or load terminals without compromising the trip unit functionality.
How do you adjust the trip settings on the PXD63B160?
The thermal element is fixed, but the magnetic instantaneous trip is adjustable. Adjustments are made using the dials on the front of the trip unit to coordinate with downstream devices.
Can the trip unit on the PXD63B160 be swapped out for a different rating?
No, this breaker comes complete with a non-interchangeable thermal-magnetic trip unit. The trip unit cannot be removed or replaced in the field.
Does the PXD63B160 mount onto standard DIN rail?
No, this is a high-amperage bolt-on circuit breaker designed to be bolted directly to the busbars in compatible Siemens switchboards and motor control centers.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection against overloads and Instantaneous (I) protection against short circuits.
What maintenance is required for the PXD63B160?
Routine maintenance includes verifying that the bolt-on connections to the busbars are torqued to the manufacturer specifications, inspecting the breaker for signs of overheating or physical damage, and exercising the mechanical toggle to ensure smooth operation.
