BF18T2A400 - 4P CONTACTOR 2NO+2NC 32A 400V 50/60HZ

Why Choose the BF18T2A400?

Lovato’s BF18T2A400 four-pole contactor delivers dependable switching for control and power circuits. With 2NO and 2NC contacts, a 32 A AC-1 rating, and AC-3 performance of 18 A / 7.5 kW at 400 V, it suits a wide range of loads. The 400 VAC 50/60 Hz coil and screw or 35 mm DIN rail mounting simplify panel integration.

Built for long service, this BF18 series device offers 20,000,000 mechanical cycles and operates from -50 to 70 °C, up to 3000 m altitude. Rated Ui 690 V and Uimp 6 kV with pollution degree 3, it ensures robust insulation performance. Terminal tightening torque of 1.5 to 1.8 Nm and compliance with IEC/EN/BS, UL and CSA standards support safe, consistent installation.
