BF18T4A048 - 4P CONTACTOR NO 32A AC1 48/50-60

Why Choose the BF18T4A048?

Engineered for dependable switching, the Lovato BF18T4A048 four‑pole contactor (SKU: BF18T4A048) delivers 32A AC1 performance and 18A/7.5kW AC3 at 400V. Its 48VAC 50/60Hz coil ensures reliable actuation, while screw or 35mm DIN‑rail mounting streamlines installation. With a robust Ui of 690V and 6kV impulse withstand, this compact unit suits control panels requiring durable, standards‑compliant operation.

Designed for longevity and harsh environments, it offers a 20,000,000-cycle mechanical life and operates from −50 to 70°C (storage −60 to 80°C) up to 3000 m altitude, pollution degree 3. Rated 10 HP at 480V (UL/CSA), it meets IEC/EN/BS 60947 and UL/CSA standards. Terminal screws tighten to 1.5–1.8 Nm, and the 362 g BF18 device simplifies panel balancing.
