BF18T0A048 - 4P CONTACTOR NC 32A 48V 50/60HZ

Why Choose the BF18T0A048?

Designed for dependable switching, the Lovato BF18T0A048 four‑pole contactor delivers robust performance in compact panels. With a 48 VAC 50/60 Hz AC coil and a 4NC configuration, it supports Ith (AC1) 32 A and AC‑3 18 A / 7.5 kW at 400 V. Screw or 35 mm DIN rail mounting simplifies installation, while high insulation (Ui 690 V) and 6 kV impulse withstand support demanding industrial environments.

Built on the BF18 series, this contactor is engineered for endurance with a mechanical life of 20,000,000 cycles and operation from −50 to 70 °C. It carries UL/CSA horsepower rating of 10 HP at 480 V and conforms to IEC/EN/BS 60947‑1 and 60947‑4‑1, UL and CSA standards. Rated to pollution degree 3 with a 1.5–1.8 Nm terminal torque and 3000 m max altitude, it suits wide‑ranging applications.
