Product FAQs
7 answersWhich metering stacks are compatible with the CHH3100H2X tenant main breaker?
This breaker is designed exclusively for use in Eaton and Cutler-Hammer commercial modular metering stacks, specifically the 35MM, 37MM, 35SS, and 37SS series.
What does the H2X suffix mean in the CHH3100H2X part number?
The H2X suffix designates the interrupting capacity of the breaker. In the CHH frame family, H2X indicates a 25kAIC rating at 240V AC, distinguishing it from higher capacity variants like the H4X or X models.
What wire sizes are supported by the lugs on this breaker?
The factory-installed lugs accept conductor sizes ranging from #2 AWG up to 300 kcmil. They are rated for use with both copper and aluminum wiring.
Are the trip settings on the CHH3100H2X adjustable?
No, this breaker utilizes a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. It does not offer field-adjustable trip dials.
Is this 3-pole breaker suitable for single-phase 120/240V AC metering stacks?
No, 3-pole tenant main breakers like the CHH3100H2X are designed for three-phase 208Y/120V AC modular metering applications. Single-phase 120/240V AC stacks require a 2-pole breaker.
How is the CHH3100H2X secured inside the metering stack?
It utilizes a bolt-on connection, bolting directly to the busbar within the tenant main section of the modular metering enclosure.
Is there a newer replacement model for the CHH3100H2X?
Yes, the CHH3100H2X is eventually being replaced by the Eaton CVS3100XMM tenant main circuit breaker for future upgrades and panel replacements.
