Product FAQs
5 answersHow many panel spaces does the CH3090 require?
This 3-pole breaker requires three 3/4-inch spaces in a compatible Eaton CH loadcenter.
Can I install the CH3090 in a single-phase panel?
No. Because it is a 3-pole breaker, the CH3090 must be installed in a 3-phase Eaton CH loadcenter.
Is the Eaton CH3090 HACR rated?
Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration motor loads.
Is the Eaton CH3090 interchangeable with Cutler-Hammer or Challenger versions?
Yes. Eaton acquired Cutler-Hammer and Challenger. The CH3090 is the exact same component across these legacy brand names and is fully interchangeable in Type CH panels.
Does the CH3090 feature a common trip mechanism?
Yes, this breaker features an internal common trip connection. If a fault is detected on any single pole, all three poles will open simultaneously to disconnect power safely.
