Where It Works Best

The HFXD63B175 175A 3-pole circuit breaker is best suited to compatible commercial and industrial electrical distribution equipment, particularly existing or legacy systems designed around the HFXD6 Sentron frame. It makes sense for maintenance and replacement situations where preserving the original breaker configuration and electrical characteristics is the objective—not changing the system to a different breaker design.
