Why Choose the Lovato BF50T4A048 4-Pole Contactor?
The Lovato BF50T4A048 is a robust four-pole power contactor designed for reliable switching of industrial electrical loads, motors and power circuits. As part of the Lovato BF50 contactor series, it provides high switching capacity in a compact format suitable for industrial machinery, automation equipment, distribution systems and electrical control panels.
This contactor has an IEC conventional free-air thermal current (Ith) and AC-1 operational current of 90 A at up to 40 °C. Its four-pole configuration enables simultaneous switching of four conductors, making it particularly useful for power distribution, resistive-load switching and applications where an additional pole is required alongside conventional three-phase switching.
The BF50T4A048 incorporates a 48 V AC 50/60 Hz control coil and is also rated for 50 A AC-3 at 400 V, corresponding to 22 kW AC-3 operational power. Flexible screw or 35 mm DIN rail mounting supports straightforward installation in industrial control cabinets and switchgear assemblies.
