The SOL80SPDR3P10 is a terminal extension for the Schneider Electric EasyPact Solar MCCB range, rated 800 A across three poles with an 80 mm connection pitch. It uses copper conductors and mounts straight, with connection points both upstream and downstream. This is the accessory that adapts the MCCB's line and load terminals to a fixed 80 mm busbar or cable spread — a common requirement for solar combiner boxes and DC switchboards where phase spacing is standardized.
The 800 A rating matches the EasyPact Solar MCCB's full-frame current — this extension does not derate the breaker when used with copper conductors within its specified cross-section range. The 80 mm pitch is the center-to-center distance between poles; it aligns with standard busbar drilling patterns used in solar DC distribution and many switchboard layouts. If your panel's busbar pitch is 60 mm or 100 mm, this extension will not align without adapters. Three poles (3P) means it handles a three-wire DC circuit — typical for ungrounded PV arrays or three-phase AC downstream of the inverter. The straight mounting position and upstream/downstream connection points give flexibility in cable routing within the enclosure.
