The Schneider Electric TeSys WB1HA300 is a replacement contactor coil designed for the CV1B and CV3B contactor frames. It's a low-consumption AC/DC coil rated at 305 V AC at 50 Hz and 348 V AC at 60 Hz — so if your line runs on 50 Hz mains, the coil sees 305 V; on 60 Hz it sees 348 V. That split matters when you're ordering a drop-in spare for a specific plant voltage.
