BF115T4A110 Lovato contactor 4 pole AC3:115A 55kw 110VAC coil

Why Choose the BF115T4A110?

Engineered for demanding switching duties, the Lovato BF115T4A110 four‑pole contactor combines a 160 A AC1 rating with 115 A/55 kW AC3 performance at 400 V. Its 110 VAC 50/60 Hz AC coil ensures reliable actuation, while flexible screw or 35 mm DIN rail mounting speeds panel integration. Built on the proven BF115 platform, it suits rigorous industrial control and power distribution tasks.

Rated Ui 1000 V with 8 kV impulse withstand, this device offers robust insulation for harsh environments. A mechanical life of 15,000,000 cycles and 6–7 Nm terminal torque underline durability and secure terminations. Operating from −50 to 70 °C up to 3000 m, it weighs 2420 g and meets IEC/EN/BS, UL and CSA 60947 standards, with a Sustainability certification for responsible selection.
