Lovato 11B115SL0048 heavy-duty three-pole industrial contactor with 48 V AC/DC coil, 110 A AC-3 operational current rating and compatibility with G495 mechanical latch systems for industrial automation and motor control applications.
The Lovato 11B115SL0048 is a heavy-duty three-pole power contactor designed for dependable switching of industrial motors and high-current electrical loads. Part of the proven Lovato B115 contactor series, this model features a 48 V AC/DC operating coil and is prepared for installation of the optional Lovato G495 mechanical latch.
Engineered for demanding industrial environments, the B115 contactor combines high switching capacity, durable construction and long operational life. Its screw-mounted format allows secure installation inside electrical control panels, motor control centres and OEM machinery.
With an IEC AC-3 operating current of 110 A, a conventional free-air thermal current of 160 A and a rated motor power of 61 kW at 400 V, the 11B115SL0048 is suitable for controlling substantial three-phase motor loads. The contactor is supplied without a mechanical latch, allowing the compatible G495 accessory to be selected separately when maintained operation is required.
Power contactors such as the Lovato 11B115SL0048 allow industrial motors and other high-current loads to be controlled from a lower-power automation circuit. Its 110 A AC-3 operating rating and 61 kW motor rating at 400 V make it suitable for demanding machinery, processing equipment and material handling systems.
The contactor is prepared for the optional Lovato G495 mechanical latch, allowing it to be adapted for maintained switching applications. When the compatible latch is installed, the selected contact position can be mechanically retained after the operating signal is removed, reducing the need for continuous coil energisation.
