Product FAQs
7 answersWhat equipment is the CHH3225 breaker designed to fit?
This 3-pole tenant main breaker is designed for installation in Eaton modular metering stacks, specifically the 35MM, 37MM, and 37SS series enclosures.
What wire sizes are accepted by the lugs on this breaker?
The factory-installed lugs accept copper or aluminum wire ranging from #2 AWG to 300 kcmil.
Is there a direct replacement available for the CHH3225?
Yes, Eaton designates the CVH3225X as the modern replacement for this frame, maintaining the 100kAIC rating and physical compatibility for metering stacks.
What does the 100kAIC rating indicate for this tenant breaker?
The 100kAIC rating means this breaker can safely interrupt up to 100,000 amps of fault current at 240VAC, making it suitable for commercial metering applications with high available fault currents.
How does this breaker mount into the metering stack?
It utilizes a bolt-on connection to secure directly to the buswork of compatible Eaton modular metering enclosures, providing a stable and reliable connection for heavy commercial loads.
What type of trip unit is equipped on this model?
It features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions to protect against both sustained overloads and sudden short circuits.
What does the feed-thru connection type mean for this breaker?
A feed-thru configuration means the breaker is designed to pass power directly from the line side bus to the load side lugs, which is standard for tenant main disconnects in modular metering.
