Description

Rated for up to 600VAC and 250VDC, this 400-amp unit-mount motor circuit protector delivers specialized magnetic-only defense. It installs seamlessly into industrial motor starters to interrupt severe short circuits before equipment damage occurs. While it serves as a reliable replacement for existing L-Frame setups, modern facilities frequently substitute it with the PowerPacT LGL36400U31X. The device features an adjustable 500 to 1000-amp trip range to accommodate specific motor profiles.
