BF18T0L024 - 4P CONTACTOR NC 32A AC1 24VDC L.C.

Why Choose the BF18T0L024?

Engineered for dependable switching, the Lovato BF18T0L024 four-pole contactor (4NC) pairs a low-consumption 24VDC coil with robust current ratings: 32 A Ith (AC1) and 18 A/7.5 kW AC3 at 400 V. Part of the BF18 series, it supports screw or 35 mm DIN rail mounting and offers a 690 V rated insulation voltage with 6 kV impulse withstand. Built to international standards, it is a versatile choice for industrial control panels and machinery builders.

With a mechanical life of 20,000,000 cycles and UL/CSA 10 HP at 480 V, this BF18 contactor delivers reliability in demanding environments. It operates from -50 to 70 °C (storage -60 to 80 °C), at altitudes up to 3000 m, pollution degree 3. Secure connections are ensured with 1.5 to 1.8 Nm terminal torque. At 502 g, it installs neatly in panels where consistent performance matters.
