BF18T0D125 - 4P CONTACTOR NC 32A AC1 125VDC

Why Choose the BF18T0D125?

Lovato BF18T0D125 is a robust four-pole contactor engineered for reliable control and isolation in industrial assemblies. With a 125 V DC coil and 4NC contacts, it provides AC1 Ith of 32 A and AC3 performance of 18 A/7.5 kW at 400 V. Flexible screw or 35 mm DIN rail mounting streamlines installation and panel integration for motors, drives, and resistive loads.

Built for demanding environments, this BF18 series device offers Ui 690 V and Uimp 6 kV dielectric strength, plus a mechanical life of 20,000,000 cycles. It operates from -50 to 70 °C and up to 3000 m altitude, with pollution degree 3. Rated 10 HP at 480 V (UL/CSA), and secure terminations use 1.5–1.8 Nm torque. Conforms to IEC/EN/BS, UL and CSA 60947 standards.
