BF26T0D012 - 4P CONTACTOR NC 45A AC1 12VDC

Why Choose the BF26T0D012?

The Lovato BF26T0D012 four-pole contactor delivers reliable switching for AC‑1 loads up to 45A. Equipped with a 12V DC coil and 4NC main contacts, this compact unit suits control panels requiring dependable isolation and interlocking. Rated insulation voltage is 690 V with 6 kV impulse withstand, and it mounts via screws or on a 35mm DIN rail for fast installation.

Engineered for endurance, the BF26 series offers 20,000,000 mechanical cycles and operates from −50 to 70 °C, up to 3000 m altitude (pollution degree 3). It carries UL/CSA approvals with a 15 HP rating at 480 V and conforms to IEC/EN/BS 60947-1 and 60947-4-1. Terminal torque is 2.5 to 3 Nm, supporting secure wiring in demanding environments.
