Selecting by duty category
Decide the load type before the size. Motor loads are rated by AC-3, heaters by AC-1, and plugging or jogging duty by AC-4; the datasheet lists a current for each category, and the lowest applicable one governs.
Order-code reading, derived from the catalogue entry: BF09T4 identifies the contactor size and auxiliary-contact arrangement, and the last characters give the coil voltage (230 V).
Applications and mounting
Typical uses are motor starters for pumps, fans and compressors, heater switching, and lighting or capacitor duty where the datasheet allows. With a thermal or electronic overload relay and a short-circuit device it forms a direct-on-line starter.
At 356 g the contactor is easily handled in a panel; fixing is screw or DIN rail, and the allowable mounting angle and operating temperature are in the table.
For panel design and commissioning, the practical figures to keep at hand are: operating temperature (min) -50 °C; operating temperature (max) 70 °C; operating position, normal Vertical plan; operating position, allowable ±30°; fixing Screw / DIN rail 35mm; weight 356 g. These come straight from the datasheet and are repeated here so that the key installation limits are visible without opening the PDF.
Documents and quotation
All data on this page for BF09T4A230 is taken from the Lovato Electric catalogue datasheet (English), which you can download from the attachment list. Ordering checklist: the motor current, coil voltage, the number and type of auxiliary contacts and the utilisation category of your load. Data in the datasheet is subject to change by the manufacturer. Other options are in contactors & overload relays. An RFQ for BF09T4A230 needs only the quantity and delivery location; Seven Star LLC, an independent Muscat supplier, replies with availability. The datasheet adds the full UL rating tables, coil operating limits and switching times, which matter when the contactor is part of a safety or timing-critical circuit.
