Product FAQs
8 answersWhat does the X3 suffix mean on the CV3200X3 catalog number?
The X3 suffix indicates that the breaker is equipped with load-side terminals only, featuring oversized lugs that accept up to 300 kcmil wire. Standard CV3200 breakers without this suffix have a maximum wire capacity of 4/0 AWG.
Does the CV3200X3 include both line and load lugs?
No. Because it is designed as a tenant main breaker that bolts directly to the bus in a metering stack, it features load-side lugs only. Line-side lugs are not included or required for this application.
Does the 300 kcmil lug option change the physical footprint of the breaker?
Yes. The oversized 300 kcmil load lugs require a terminal shield, which adds 1.50 inches (38.1 mm) to the overall length of the circuit breaker compared to standard models.
What metering equipment is the CV3200X3 compatible with?
This bolt-on molded case circuit breaker is designed for use in Eaton and Cutler-Hammer group metering stacks and modular metering enclosures, including the 1MM, 3MM, and 1MP series.
What legacy circuit breakers can the CV3200X3 replace?
The CV3200X3 serves as a direct, exact-fit replacement for older Cutler-Hammer CHH3200 series tenant main breakers in commercial metering applications.
Are there alternative AIC ratings available for this 200A 3-pole CV frame breaker?
Yes. While the CV3200X3 is rated for 65 kAIC at 240VAC, Eaton also manufactures the CVS3200X3 (rated at 42 kAIC) and the CVH3200X3 (rated at 100 kAIC) for applications that require different interrupting capacities.
What type of trip unit is installed in the CV3200X3?
It features a non-interchangeable thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) trip functions for reliable overload and short-circuit protection.
What wire sizes and materials are accepted by the load lugs on this breaker?
The load-side lugs are rated for both copper (Cu) and aluminum (Al) conductors ranging from 6 AWG up to 300 kcmil.
