Product FAQs
6 answersWhat equipment is the CHH2175 circuit breaker designed to fit?
This breaker is designed for use as a tenant main circuit breaker in Eaton 1MP and 1MM modular metering stacks.
How is the CHH2175 mounted inside the metering stack?
This is a bolt-on frame that secures directly to the bus bar of compatible Eaton modular metering stacks, ensuring a reliable connection for high-amperage tenant feeds.
Does the CHH2175 come with line and load lugs installed?
Yes, this feed-thru breaker includes factory-installed line and load side lugs that accept #2 AWG to 300 kcmil copper or aluminum wire.
What does the 100kAIC rating mean for this breaker?
The 100kAIC rating indicates that the breaker can safely interrupt up to 100,000 amps of fault current at 240V AC without sustaining internal damage. This high interrupting capacity is often required for commercial and multi-tenant metering centers.
Is the CHH2175 a direct replacement for older Cutler-Hammer CHH breakers of the same amperage?
Yes, the Eaton CHH2175 is the direct replacement for legacy Cutler-Hammer 175A, 2-pole CHH frame tenant main breakers used in compatible meter stacks.
Where can I find the correct lug torque specifications for the CHH2175?
Torque specifications are printed directly on the breaker specification label. Always use a calibrated torque wrench during installation to ensure a secure connection and prevent overheating, as required by the National Electrical Code.
