BF4000A230 Lovato contactor 3 pole AC3:40A 18.5kw 230VAC coil

Why Choose the BF4000A230?

The Lovato BF4000A230 is a three-pole contactor designed for dependable motor control in industrial panels. With IEC AC-3 performance of 40A at 400V (18.5 kW) and AC-1 Ith of 70A, it delivers robust switching capacity. A 230VAC AC coil rated for 50/60Hz simplifies integration with common control supplies, while the compact BF40 designation aligns with Lovato's proven contactor platform.

Engineered for demanding environments, it offers Ui 1000 V and 8 kV impulse withstand, mechanical life to 15,000,000 cycles, and operation from -50 to 70 °C. Screw or 35 mm DIN rail mounting speeds installation, and a 30 HP rating at 480 V supports UL/CSA applications. Conforms to IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents.
