Built to protect circuits against overloads and short circuits, the Eaton PDG23P0050TFFL molded case circuit breaker is rated 50A, 600VAC and 250VDC. This 3-pole, 3-phase Power Defense breaker uses the PDG2 frame and panel mounting. It provides 100kAIC interrupting capacity at 480VAC. Its thermal magnetic trip has fixed thermal and magnetic settings with long-time and instantaneous protection. Approvals include CSA, CCC, IEC, UL and CE.
When should I select the 50A Eaton PDG23P0050TFFL?
Select this 50A molded case circuit breaker when the circuit design calls for that current rating. Coordinate the selection with the calculated load and conductor ampacity.
Can this breaker be used on AC or DC circuits?
The voltage ratings are 600VAC and 250VDC. Use the rating for the circuit's current type and verify that the system voltage is within that rating.
How does the 100kAIC rating affect selection for a 480VAC circuit?
At 480VAC, the interrupting rating is 100kAIC. Compare this rating with the available fault current at the installation point, which must not exceed the breaker's interrupting rating.
Can I adjust the overload or instantaneous trip settings?
No. The thermal-magnetic trip has fixed thermal and fixed magnetic settings. Its long-time function responds to sustained overloads, while its instantaneous function responds to high short-circuit currents, so select it when fixed trip settings meet the circuit's protection needs.
What conductor sizes can I connect at the load side?
The conductor range is 14-1/0 AWG, and the load-side connection uses a standard lug. Choose a conductor within that range while also meeting the circuit's ampacity requirements.
What dimensions should I use when planning installation space?
The breaker measures 6 in high, 4.12 in wide and 3.5 in deep. Use these dimensions to plan the breaker layout and space for conductor routing.
How does the three-pole construction affect breaker selection?
The Eaton PDG23P0050TFFL has 3 poles, with a protected current path through each pole. Use the pole count when reviewing how many current paths the circuit requires the breaker to protect.
