Eaton PDG11F0020TFFJ molded case circuit breaker is a 20A, 1-pole model in the Power Defense PDG1 series, with a 25kAIC interrupting rating at 480VAC. It features fixed thermal and fixed magnetic trip settings with long-time and instantaneous trip functions. Panel mounting and standard line and load side lug connections accommodate a conductor range of 14-1/0 AWG.
How should I use the 20A rating when selecting the Eaton PDG11F0020TFFJ?
The 20A rating is the breaker’s rated current. Select it according to the circuit load and conductor ampacity, applying the electrical code requirements for the installation.
How does the single-pole construction affect circuit selection?
This breaker has one pole and is rated for single-phase applications. Use it where the circuit design calls for one protected conductor path.
Can I adjust the thermal or magnetic trip settings?
No. Both the thermal and magnetic settings are fixed. The thermal element provides long-time overload protection, while the magnetic element provides instantaneous short-circuit protection, so selection must account for the load’s operating and starting characteristics.
Which AC and DC voltage ratings can I select this breaker for?
The rated voltages are 240VAC, 480VAC, 600VAC, 125VDC and 250VDC. Match the circuit’s voltage and AC or DC service to the applicable rating when selecting the breaker.
What does the 25kAIC at 480VAC interrupting rating mean for selection?
At 480VAC, the breaker has a 25kAIC interrupting rating. The available fault current at the installation point must not exceed that rating.
What conductor sizes can the terminals accept?
The conductor range is 14-1/0 AWG. Choose a conductor within that range while also meeting the circuit’s ampacity and installation requirements; terminal acceptance alone does not determine conductor sizing.
How are the incoming and outgoing conductors connected?
The breaker has standard line-side and load-side lug connections. Connect incoming conductors to the line-side lugs and outgoing circuit conductors to the load-side lugs, maintaining the line and load arrangement during installation.
How much physical space should I plan for the breaker?
The breaker measures 5.5 in high, 1 in wide and 2.99 in deep. Use these dimensions when planning equipment layout, with room for conductor routing and access to the connections.
