Product FAQs
7 answersWhich Eaton modular metering stacks accept the CHH2100H4X breaker?
This bolt-on tenant main breaker is engineered for direct integration into Eaton 1MM, 35MM, 37MM, and 37SS modular metering enclosures.
What is the primary application for the CHH2100H4X circuit breaker?
It is primarily used as a tenant main circuit breaker in multi-family residential or commercial modular metering stacks, isolating individual tenant loads from the main service.
How is the CHH2100H4X secured within the metering center?
It utilizes a bolt-on mounting configuration to ensure a rigid, high-integrity connection to the metering stack bus, preventing arcing or loosening in multi-tenant environments.
What conductor sizes and materials are supported by the CHH2100H4X lugs?
The breaker includes load-side lugs that accommodate either copper or aluminum wiring, accepting wire gauges from #2 AWG up to 300 kcmil.
Does the CHH2100H4X provide adequate fault protection for commercial metering centers?
Yes, it features a high interrupting capacity of 42 kAIC at 120/240VAC, providing robust short-circuit and overcurrent protection for tenant main circuits where elevated fault currents are present.
How does the thermal-magnetic trip unit on the CHH2100H4X operate?
The fixed thermal-magnetic (LI) trip mechanism provides dual protection. The thermal element responds to sustained overcurrents, while the magnetic element trips instantaneously in the event of a severe short circuit.
Can the CHH2100H4X be used to replace older tenant main breakers in Cutler-Hammer stacks?
Yes, this breaker is a direct OEM replacement for legacy Cutler-Hammer and Eaton CHH-frame 100A tenant main breakers in compatible modular metering centers.
