Product FAQs
7 answersWhat legacy Cutler-Hammer circuit breakers does the PDG33M0350TFAJ replace?
This Power Defense Frame 3 breaker serves as a direct upgrade and replacement for older legacy Cutler-Hammer molded case circuit breakers, specifically the HKD3350 and LGH3350 models.
Which electrical panelboards accept this Frame 3 breaker?
It is engineered for seamless installation into Eaton Pow-R-Line panelboards and Eaton Power Defense Frame 3 panelboards.
How is the thermal-magnetic trip unit configured on this model?
The TFAJ suffix indicates a thermal-magnetic trip unit with a fixed thermal overload rating of 350A and an adjustable magnetic instantaneous trip for selective coordination. The J confirms standard line and load lugs are factory installed.
What wire sizes are supported by the factory-installed lugs?
The standard line and load terminals accept a single conductor from 2 AWG to 500 kcmil, or dual conductors from 3/0 AWG to 250 kcmil. The terminals are dual-rated for aluminum and copper (Al/Cu) wire.
What performance tier does the PDG33M0350TFAJ fall under?
The M in the catalog string designates Eaton's Medium interrupting capacity tier, delivering a 65 kAIC rating at 480VAC and up to 100 kAIC at 240VAC.
Can this 350A breaker be used for commercial HVAC equipment loads?
Yes. Like most modern UL 489 thermal-magnetic breakers in this class, it is fully HACR rated for safe use with heavy heating, air conditioning, and refrigeration systems.
Does this molded case circuit breaker support direct current (DC) applications?
Yes, it is rated for DC power distribution, providing an interrupting capacity of 22 kAIC on 250VDC systems.
