BF11500A024 Lovato contactor 3 pole AC3:115A 55kw 24VAC coil

Why Choose the BF11500A024?

Engineered for reliable motor switching, the Lovato BF11500A024 (SKU BF11500A024) is a three‑pole contactor with a 24VAC 50/60Hz coil. It delivers 115A AC‑3 at 400V (55kW) and 160A AC‑1, with Ui 1000V and Uimp 8kV for robust insulation. Flexible screw or 35mm DIN rail mounting simplifies panel integration, while compliance to IEC/EN/BS and UL/CSA standards supports use in international control panels.

Designed for harsh environments, this BF115 contactor operates from -50 to 70°C and up to 3000m altitude, with a mechanical life of 15,000,000 cycles. The 75HP rating at 480V under UL/CSA suits North American systems, and terminals accept 6–7Nm tightening torque for secure connections. Choose the Lovato BF11500A024 to standardise on dependable, high‑performance motor control across pumps, fans, compressors and conveyors.
