SPD1K0125 Eaton 125 A Circuit Breaker Enclosure, NEMA 1, 3-Pole, Accepts PD1

Trying to find the correct housing for a three-pole Eaton Power Defense breaker? That is what the SPD1K0125 is for. It holds the breaker, mounts to the surface of an indoor wall, and carries a NEMA 1 rating, the basic indoor rating covering contact with live parts and falling dirt. Eaton lists the amperage rating as 125 A.

Two details are worth confirming first. Eaton lists SPD1K0125 as accepting a PD1 frame, three-pole, 125 A frame MCCB, which is Eaton's Power Defense line. The Eaton catalog note also says this Power Defense enclosure is not approved for Series C/G MCCB, so an older Series C or Series G breaker is not what Eaton pairs with it. Eaton publishes the product size as 20.1 in H x 11.2 in W x 10.7 in D and the product weight as 12.9 lb.
