The Lovato 11B500SL00380 is a heavy-duty 3-pole power contactor engineered for reliable switching of high-current industrial motors and power circuits. Part of the proven Lovato B500 contactor series, it is designed for demanding motor control, power distribution and industrial automation applications where dependable performance and long service life are essential.
This model features a 380–415 V AC/DC universal control coil and is predisposed for the optional G495 mechanical latch, allowing future conversion to maintained-contact operation when required. The universal AC/DC coil simplifies panel design while providing flexible integration into industrial control systems.
With an IEC AC-1 thermal current rating of 700 A, an AC-3 operational current of 520 A at 400 V, and the capability to switch motors up to 290 kW, the 11B500SL00380 is designed to deliver reliable switching performance in the most demanding industrial environments.
The Lovato B500 series is designed for switching high-current industrial motors and heavy electrical loads with exceptional reliability. Its robust construction, universal AC/DC coil and high insulation ratings provide dependable operation across industrial automation systems, manufacturing facilities and motor control centres.
Being prepared for the optional G495 mechanical latch provides additional flexibility by allowing maintained-contact functionality to be added without replacing the complete contactor, making it suitable for evolving industrial control systems.
