Product FAQs
8 answersWhat equipment is the D16AB150 circuit breaker designed to fit?
This legacy breaker is engineered for installation in older Gould and I-T-E panelboards and switchboards.
How does the D16AB150 achieve its 100kA interrupting capacity?
This breaker utilizes integral fuses to provide a high interrupting rating of 100kA across all supported voltages, including 600VAC and 250VDC.
What protection functions are provided by the thermal-magnetic trip unit?
The trip unit provides long-time (L) and instantaneous (I) protection, safeguarding electrical systems against both sustained overloads and sudden short circuits.
What are the lug wire size requirements for the D16AB150?
The factory-installed lugs accommodate conductors ranging from 4 AWG up to 300 kcmil. Ensure proper torque specifications are followed during installation.
Does the D16AB150 plug into the panel bus?
No, this is a unit-mount circuit breaker. It must be bolted securely to the enclosure or mounting pan and hardwired, rather than plugging directly onto a busbar.
Why is the D16AB150 listed under Siemens, Gould, and I-T-E?
Gould and I-T-E are legacy brands that were acquired by Siemens. The D16AB150 may carry any of these manufacturer labels depending on its production date, but the physical footprint and specifications remain identical.
Is the D16AB150 considered a C-frame breaker?
Yes, despite the D prefix in the catalog number, this model is classified within the legacy C-frame group of molded case circuit breakers.
Is the D16AB150 suitable for direct current (DC) applications?
Yes, in addition to its AC ratings, this breaker is fully rated for DC systems up to 250VDC with a maximum interrupting capacity of 100kA.
