Product FAQs
4 answersWhat equipment is the CV3150X designed to be installed in?
This breaker is specifically designed for use as a tenant main breaker in Eaton and Cutler-Hammer group metering stacks, including 1MM, 3MM, and 1MP modular metering units.
What does the "X" suffix in the CV3150X catalog number indicate?
The "X" suffix indicates that the breaker is configured with load-side lugs only. The line side is designed to bolt directly onto the busbar within compatible Eaton metering stacks.
Can I install the CV3150X in a standard residential load center?
No. This is a specialized bolt-on tenant main breaker designed exclusively for group metering stacks. It lacks line-side lugs and will not mount or wire correctly in standard plug-on or bolt-on panelboards.
Is this a direct replacement for legacy Cutler-Hammer CHH breakers?
Yes, the CV3150X serves as an exact drop-in replacement for the legacy Cutler-Hammer CHH3150 tenant main breaker used in older group metering applications.
