LD63T600 - 600Amp Trip Unit

LD63T600 - 600Amp Trip Unit

The LD63T600 is a 600-amp, 3-pole thermal-magnetic trip unit intended for an LD frame application. The manufacturer identifies this catalog number as "TU ONLY," an important distinction when you're sourcing a replacement for existing electrical equipment. When the catalog number and application requirements line up, the LD63T600 can serve as a form, fit, and functional replacement for equipment designed around this configuration. Properly selected, installed, and used within its specified ratings and application, it is built to last.

Where It Works Best

The LD63T600 is best considered when existing or legacy electrical equipment specifically calls for a 600A, 3-pole thermal-magnetic trip unit for an LD frame. Rather than choosing a replacement based on amperage alone, match the complete electrical configuration to the equipment documentation.

Pay particular attention to the interrupting ratings: 25kA at 600V and 35kA at 480V. The applicable rating must meet the installation requirements and the available fault current.
