BF09T4A048 - 4P CONTACTOR NO 25A AC1 48/50-60

Why Choose the BF09T4A048?

Lovato’s BF09T4A048 four-pole contactor (SKU: BF09T4A048) delivers dependable switching for control and power circuits. With a 48VAC 50/60Hz coil and AC1 Ith of 25A, it handles resistive loads with confidence, while AC3 performance is 9A/4.2kW at 400V. Screw or 35mm DIN rail mounting simplifies panel integration, with BF09 product designation and compliance to IEC/EN/BS 60947 standards.

Engineered for demanding environments, this contactor offers 690 V rated insulation (Ui) and 6 kV impulse withstand (Uimp), with mechanical life up to 20,000,000 cycles. It operates from -50 to 70 °C and can be stored from -60 to 80 °C, up to 3000 m altitude, pollution degree 3. Terminals tighten to 1.5–1.8 Nm for secure connections, with a compact 368 g build.
