Eaton PDG Series 20 A Circuit Breaker

This single-pole circuit breaker from the Eaton PDG series is rated at 20 amps and 600 V AC for commercial and industrial electrical panels. It uses a thermo-magnetic trip unit with a fixed instantaneous setting to provide overload and short-circuit protection on a three-phase system.

25 kA interrupting capacity at 480 V AC

The breaker delivers a maximum AIR rating of 25 kA at 480 V AC, giving ample headroom for typical panel fault levels in this class. It accepts conductors from 14 AWG up to 1/0 AWG on standard load-side terminals and fits within a 225 A frame size.

Rated for 158 °F maximum operating temperature

The device is designed to operate continuously in environments up to 158 degrees Fahrenheit without derating its protective characteristics. Its compact dimensions of 6 inches high, 1.38 inches wide and 3.5 inches deep allow dense mounting in standard enclosures while maintaining thermal performance.

Questions about this item

Will the 1-pole 20 A breaker fit in the same Power Defense panel that currently holds a 225 A frame unit?

Yes, the breaker uses the Frame Size 225 A / Frame 2 form factor so it mounts directly in the existing Power Defense panel.

How can I confirm the thermo-magnetic trip is operating correctly after installation?

Apply rated current and verify the fixed instantaneous trip opens the circuit; the breaker carries 20 A continuously and trips only on overcurrent per its thermo-magnetic curve.

Does the package include line-side terminals or must they be ordered separately?

The breaker ships with standard load-only terminals for 14 AWG to 1/0 AWG wire; line-side terminals are not included and must be sourced separately.
