The description 'CONT 3P 2F2O 48V-50HZ' decodes as a 3-pole contactor with two normally-open and two normally-closed auxiliary contacts, controlled by a 48 V AC coil rated at 50 Hz. The 48 V 50 Hz coil means this part is specific to 50 Hz mains regions — it will not pull in reliably on a 60 Hz supply at the same voltage without derating the coil voltage. Verify the line frequency before specifying this as a drop-in replacement.
The 2NO+2NC built-in aux contacts cover most feedback and interlocking needs without an external block.
