Product FAQs
6 answersWhat equipment is the CHH2150 designed to be installed in?
This breaker is specifically designed for use as a tenant main breaker in Eaton modular metering stacks, including the 1MM, 35MM, 37MM, 35SS, and 37SS series enclosures.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory-installed lugs accept copper or aluminum conductors ranging from 2/0 AWG to 300 kcmil.
How does the CHH2150 connect to the metering stack bus?
It features a bolt-on mounting style, ensuring a secure, vibration-resistant connection to the metering stack busbars.
What does the 100kAIC rating signify for this specific breaker?
The 100kAIC rating indicates the maximum fault current this breaker can safely interrupt at 240VAC without sustaining damage. This high interrupting capacity makes it suitable for commercial or industrial metering applications with high available fault currents.
Are there lower interrupting capacity versions of this 150A tenant main breaker available?
Yes. If your application does not require a 100kAIC rating, Eaton offers the CH2150 for 10kAIC, the CHH2150H2X for 25kAIC, and the CHH2150H4X for 42kAIC.
What type of trip mechanism does the CHH2150 utilize?
It uses a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against sustained overloads, while the magnetic component provides instantaneous protection against short circuits.
