Product Identity

The Eaton PDG23F0040TFFL is a new molded case circuit breaker rated at 40 amps with three poles for three-phase AC systems. It belongs to the PDG series and uses a standard thermal-magnetic trip mechanism. This device suits electrical contractors and facility engineers who need branch-circuit protection in industrial panels.

Interrupting Rating

The single specification that decides fit is the maximum AIR rating of 25 kA at 480 volts AC. Verify that the available fault current at the installation point does not exceed this value. The breaker carries a 600 volt AC voltage rating and is not rated for DC applications.

Thermal And Power Profile

Thermal-magnetic operation means the breaker trips on sustained overloads through a bimetal element and on short circuits through a fixed instantaneous magnetic trip. It operates reliably between -4 degrees F and 158 degrees F. Standard load-only terminals accept copper conductors from 14 AWG up to 1/0 AWG. The frame size is 225 amps.

Questions about this item

What does the 40 A rating mean for the circuits I protect?

It means the breaker will carry up to 40 A continuously and trip on overloads or short circuits above that level to protect the downstream wiring and equipment.

How does the 25 kA AIR rating at 480 V AC limit the fault current this breaker can interrupt?

The breaker is tested to safely interrupt fault currents up to 25 kA at 480 V AC; available fault current at the installation point must not exceed that value.

What panel space and wire sizes are required to install this 3-pole unit?

The frame measures 6 in high, 4.11 in wide and 3.5 in deep, and accepts copper conductors from 14 AWG up to 1/0 AWG on the load-side terminals.
