Description
Built for commercial and industrial environments, the Eaton CHH3060 is a 3-pole, 60A molded case circuit breaker. It utilizes thermal-magnetic trip technology to provide robust long-time and instantaneous protection for three-phase systems. This bolt-on unit installs into Eaton modular metering stacks, including the 35MM, 37MM, and 37SS series. It operates as a tenant main disconnect and is the predecessor to the CVH3060X. It boasts a 100 kAIC rating at 240VAC and is HACR rated.Specifications

Product FAQs
7 answersWhich metering stacks are compatible with the CHH3060 circuit breaker?
This breaker is specifically designed for use as a tenant main in Eaton and Cutler-Hammer modular metering stacks, including the 35MM, 37MM, and 37SS series.
Why is a 100kAIC rating necessary for this 60A tenant main breaker?
High fault current ratings like 100kAIC are frequently required by local utilities in densely populated areas or large multi-family buildings. The CHH3060 safely interrupts these massive potential fault currents in group metering applications.
What system voltages is the CHH3060 designed to support?
The CHH3060 is rated for a maximum of 240VAC. It is typically deployed in 208Y/120V three-phase or standard 240V systems for multi-tenant residential and commercial metering distribution.
What are the wiring requirements for the CHH3060 feed-thru lugs?
The lugs accept #6 AWG to 4/0 kcmil copper or aluminum wire. When terminating aluminum conductors, electricians should wire brush the stripped portion and apply a listed corrosion-inhibiting joint compound to prevent oxidation and overheating.
How is the CHH3060 secured inside the metering stack?
It features a bolt-on mounting style. The breaker bolts directly to the buswork of the modular metering stack, providing a secure, high-capacity connection that resists loosening from thermal cycling.
Is the Eaton CHH3060 the same as the Cutler-Hammer CHH3060?
Yes. Eaton acquired Cutler-Hammer, and they continue to manufacture this breaker under the same CHH3060 catalog number. It serves as a direct, drop-in replacement for legacy Cutler-Hammer installations.
Can the trip curve on the CHH3060 be adjusted for specific tenant loads?
No. This breaker utilizes a fixed thermal-magnetic trip unit with standard long-time and instantaneous (LI) protection. The trip thresholds are factory calibrated and cannot be modified in the field.
