I am a fabricator that builds customized control panels. Some of these will require internal circuit breakers. This particular breaker (which is NOT designed to be mounted inside a factory made Square D or Homeline panel) can be mounted inside a custom panel in several ways. It fits on a DIN rail, which is what I use. Being a feed through it means that the switching circuit is not directional. Typical Square D product, came in OEM packaging with all mounting hardware and installation instructions (including in English). Says its made in Mexico, but this is okay with me because it doesn't appear to have any impact on quality.
