Product FAQs
8 answersHow should I use the 175A rating when selecting the Eaton PDD23G0175TFFL?
Use the 175A rated current when coordinating the breaker with the circuit load and conductor ampacity. Its thermal trip is fixed, so select the required current rating rather than planning to adjust the thermal setting.
What does the 240VAC rating mean for circuit selection?
Check that the circuit's operating voltage is within the 240VAC rating. Evaluate voltage and interrupting capacity separately, since they address different electrical requirements.
How do I evaluate the 65kAIC interrupting rating?
The interrupting rating is 65kAIC at 240VAC. Compare the available fault current at the installation point with this rating; it must not exceed the breaker's interrupting capacity.
How does the thermal-magnetic trip operate, and can I adjust it?
The thermal element provides long-time overload protection, while the magnetic element provides instantaneous response to short-circuit current. Both elements are fixed, so selection must account for the circuit's protection needs without relying on trip adjustment.
How do the pole count and phase rating guide selection?
This is a 3-pole breaker for a 3-phase circuit. Use those characteristics when selecting protection for the circuit's phase conductors.
What conductor sizes can I use, and what is the load-side connection?
The conductor range is 4 AWG through 4/0 AWG, and the load-side connection is a standard lug. Select a conductor within that range while also meeting the circuit's ampacity requirements.
What mounting method and dimensions should I account for during installation planning?
Plan for unit mounting and dimensions of 5.9 in high, 6.4 in wide and 7.9 in deep. Use these dimensions to establish the space occupied by the breaker in the installation layout.
What operating temperature range should I account for?
The operating temperature range is -4 to 158 °F. Check the expected temperature where the breaker will operate against this range when planning the installation.
