Product FAQs
6 answersWhat types of enclosures is the Eaton CAH2100 designed to fit?
This breaker is specifically designed for use in Eaton and Cutler-Hammer metering stacks and group metering applications, which are commonly used in multi-tenant residential or commercial buildings.
What wire sizes do the lugs on the CAH2100 accept?
The standard lug terminals on this breaker accommodate wire gauges ranging from #6 AWG up to 350 kcmil.
How is the CAH2100 installed in a metering setup?
It features a unit mount design with a feed-thru connection, allowing it to be bolted directly into compatible Eaton group metering enclosures.
What does the 22kAIC rating mean for this metering breaker?
The 22kAIC rating indicates that the breaker can safely interrupt up to 22,000 amps of fault current at 240V AC. This high interrupting capacity provides robust short circuit protection for tenant main applications.
How does the thermal magnetic trip unit protect the circuit?
The breaker uses fixed Long-Time and Instantaneous (LI) trip functions. The thermal component prevents overheating from prolonged mild overloads, while the magnetic component trips the breaker instantly during severe short circuits.
Is the CAH2100 suitable for single-phase power systems?
Yes, this 2-pole breaker is designed for 1-phase, 240V AC electrical systems commonly found in residential and light commercial metering centers.
