Fixed front terminals and UL listing make it a direct fit for North American panelboards and switchboards where 800 A branch or feeder protection is specified.
The 800 A frame and EKIP DIP LS/I electronic trip provide adjustable long-time (L) and short-time (S) protection plus instantaneous (I) overcurrent response. That means you can coordinate selectivity downstream — set the long-time pickup to match cable ampacity and the short-time band to ride through motor starting inrush without nuisance tripping. The 3-pole fixed configuration suits it for bolted-in switchboard mounting where drawout isn't required.
