Eaton’s Classified Circuit Breakers deliver on safe installation and reliable operation. Eaton Classified replacement Circuit Breakers are available in both 3/4-inch Type CHQ and 1-inch Type CL, single- and two-pole configurations. These breakers are UL-listed and designed to be used in loadcenters made by other manufacturers.
Specified breakers are listed by the manufacturer of the panelboard for use in a particular panel. This doesn’t mean that the panelboard manufacturer produced the specified breaker; it merely means that the panelboard manufacturer has tested the breaker in the panel. In fact, through the years, Eaton has manufactured thousands of breakers for other panelboard manufacturers. UL classified breakers are produced by one manufacturer for use in place of the breakers specified on the panelboard. Like specified breakers, UL classified breakers have been tested in the panels for which they are approved.
Classified breakers are tested extensively in numerous Square D® panels. The tests are conducted with witnesses from UL and involve short-circuit, temperature, and insertion/ withdrawal applications. This level of testing ensures that the breakers meet identified standards and have been found suitable by UL for the specified purpose.
Type CHQ breakers are a direct replacement for Square D QO type.
