Part identity and ratings
The Schneider Electric TeSys B CV1BF3F0ZM522 is a 3-pole contactor rated for 80 A in AC-3 duty at 690 V AC, meaning it handles motor switching up to that current under typical starting conditions. The coil pulls in on 220 V AC at 50 Hz. Auxiliary contacts are built in as 2 NO + 2 NC, so no separate block is needed for basic feedback or interlocking.
Application and utilisation
Rated for both AC-3 (motor starting) and AC-1 (resistive loads such as heating and lighting). The 80 A AC-3 figure governs the motor load it can switch; for resistive circuits the current rating is typically higher.
