Product FAQs
6 answersWhich panelboards accept the EH2050 circuit breaker?
This bolt-on breaker is specifically designed to mount into Eaton Pow-R-Line panelboards, switchboards, and motor control centers. It is not interchangeable with standard residential plug-on load centers.
Are Eaton, Cutler-Hammer, and Westinghouse EH2050 breakers interchangeable?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse electrical distribution lines. The EH2050 catalog number is identical across these brands and functions as a direct replacement for legacy E-frame installations.
What is the modern upgrade for the legacy EH2050 breaker?
If you are upgrading your system, the legacy EH2050 is commonly replaced by the EHD2050 model. The EHD2050 provides equivalent 50A, 2-pole protection in a newer frame style.
Is the EH2050 rated for use with HVAC systems?
Yes, this breaker carries an HACR rating, meaning it is tested and approved to handle the specific inrush currents associated with heating, air conditioning, and refrigeration equipment.
What wire gauge is required for the EH2050 terminals?
The factory-installed lugs accept wire sizes from 14 AWG up to 1/0 AWG. Installers must verify that the selected wire size matches the 50A circuit requirements and is torqued to Eaton specifications.
Does the EH2050 support direct current (DC) circuits?
Yes, in addition to its AC ratings, the EH2050 is certified for DC applications. It provides a 10kAIC interrupting rating at 250VDC, making it suitable for industrial control or battery systems.
