Designed for maximum configuration flexibility, the Eaton PDG43G0800TFAN is an 800A, 3-pole Power Defense circuit breaker. It fits into Eaton Pow-R-Line 4 panelboards and switchboards. Supplied without line or load lugs, it allows engineers to select the exact terminal kits required for their wiring needs. The breaker features a thermal-magnetic trip unit with fixed thermal and adjustable magnetic (LI) protection. It delivers a 35kAIC interrupt rating at 480VAC and is RoHS compliant.
What Eaton equipment is compatible with the PDG43G0800TFAN breaker?
This Power Defense Frame 4 circuit breaker is engineered specifically for Eaton Pow-R-Line 4 panelboards, as well as compatible switchboards and motor control centers.
How do I configure the trip unit on the PDG43G0800TFAN?
This breaker features a thermal-magnetic trip unit with fixed thermal and adjustable magnetic settings. While the continuous current rating is fixed at 800 amps, the installer can adjust the instantaneous magnetic trip dial to coordinate short-circuit protection with downstream devices.
Is the PDG43G0800TFAN suitable for DC applications?
Yes, in addition to its standard AC ratings, this breaker is rated for 250VDC systems, providing up to 22kA of interrupting capacity for direct current installations.
What type of physical connections are required for this breaker?
The PDG43G0800TFAN requires a bolt-on connection to mount directly to the panel bus. It is supplied with standard lug terminals for terminating the line and load conductors.
What type of fault protection does the LI trip unit provide?
The LI designation indicates Long-Time and Instantaneous protection. The Long-Time function protects the circuit against sustained overloads, while the Instantaneous function immediately clears high-level short circuits to prevent equipment damage.
