Overview
The LV481203 is a Schneider FuPacT GS cage terminal rated 400 A, accepting one bare Cu/Al cable from 50 mm² to 300 mm² per pole, supplied as a set of 3 parts for 3-pole switch-disconnectors. It mounts fixed to the switch base and is built in an aluminium/copper enclosure; it is a connection accessory, not a standalone switch.
The LV481204 is the 4-pole sibling of this terminal set; it shares the same 400 A rating, cable range, and enclosure material but adds a fourth pole. Pick the LV481204 when the BOM calls for 4 poles rather than 3.
