The TeSys B CV1BF2F0ZM511 is an 80 A, 2-pole contactor from Schneider Electric's TeSys range, designed for switching motor loads and resistive circuits like heating and lighting under AC-1 and AC-3 utilisation categories. The 220 V AC 50 Hz coil makes it a straight swap for existing AC-coil panels — no DC supply conversion needed on site.
Rated 80 A in AC-3 duty at 690 V AC means it handles a motor load up to that current during starting and running — the AC-3 category covers squirrel-cage motors with inrush up to 6-8× rated. The 2 NO power poles and auxiliary 1 NO + 1 NC give you basic three-wire control without an extra aux block, saving DIN rail space. If your line runs 400 V instead of 690 V, the same 80 A rating holds — just check the motor FLA against the contactor's thermal curve.
