High quality genuine Square-D breaker for QO panel, no issues
Fits QO load center and operates as advertised, no issues, and about $10 less than at local Home Despot and Loew's, if you're willing to wait 5-10 days for free shipping. Screw contacts for load wires are "new improved" half-conical design vs. the older "flat crusher" style in older designs, which is a nice improvement especially for stiff 6-ga Al stranded wire. Screw threads are combo standard+philips cross, with sufficiently deep slots that it's easy to tighten them down hard. In short, it's a standard Square-D quality breaker, no surprises.

Dependable Square D Product
Needed a higher capacity breaker for an air conditioner upgrade for my Square D Panel. Even though an older panel, this breaker fit perfectly and took less than five minutes to change out. Dependable quality and consistency that spans decades.
