FAQs
Verify that the site meets NEMA 3R conditions and the 600V/100A rating is appropriate. Mount the unit using standard four-bolt patterns, connect conductors to the Quick Connect terminals, and ensure the neutral is switched in the fusible path. Confirm Posi-Lok reverse pin engagement, then energize after performing Eaton’s recommended functional tests.
The four-pole design provides full isolation of all conductors, while the fusible with switched neutral simplifies protection schemes and reduces required components. This configuration improves fault isolation, simplifies maintenance sequencing, and supports safer disconnects for high-current loads in 600V systems.
