The Schneider Electric CV1BF2F0ZM522 is a TeSys B contactor — a 2-pole, 80 A AC-3 device with a 220 V AC 50 Hz coil. The 80 A AC-3 rating is the motor-switching current: it governs how large a three-phase induction motor this contactor can handle under full-load starts. For resistive loads (heating, lighting) the AC-1 rating is higher, but the AC-3 figure is the one that decides motor fit. The 2 NO main poles switch the power circuit; the built-in 2 NO + 2 NC auxiliary contacts handle control interlocking or status feedback without a separate add-on block. The AC coil at 220 V 50 Hz is standard for European-panel control transformers — verify your control voltage matches before specifying.
This contactor class is used inside motor control centres, pump panels, conveyor starters, and HVAC equipment to switch motor loads and resistive heating circuits. The TeSys B series is the compact, economy line within the broader TeSys family — sized for standard-duty applications where a full-featured TeSys D or F contactor is not required.
