11B115L00380110 – 3P CONTACTOR 380/415V C/W LATCH 110VAC
Lovato 11B115L00380110 heavy-duty three-pole industrial contactor with integrated G495 mechanical latch, 380–415 V AC/DC coil and 110 A AC-3 operational current rating for industrial automation and motor control applications.
Why Choose the Lovato 11B115L00380110 Power Contactor?
The Lovato 11B115L00380110 is a heavy-duty three-pole power contactor designed for reliable switching of industrial motors and high-current electrical loads. Part of the established Lovato B115 contactor series, this model combines an AC/DC control coil rated at 380–415 V with a factory-fitted G495 mechanical latch rated at 110–125 V AC.
The contactor provides dependable switching performance for motor control centres, industrial machinery and electrical control panels. Its mechanically latched design allows the main contacts to remain in position without requiring the contactor coil to remain continuously energised, supporting efficient operation in maintained-control applications.
With an IEC AC-3 operating current of 110 A, a conventional free-air thermal current of 160 A and a rated AC-3 motor power of 61 kW at 400 V, the 11B115L00380110 is suitable for demanding three-phase motor switching and industrial automation systems.

Reliable Maintained Control for Industrial Motors
Power contactors such as the Lovato 11B115L00380110 provide electrically controlled switching for three-phase motors and industrial power circuits. The contactor’s high AC-3 current rating enables it to handle the frequent starting and stopping demands associated with motor loads.
The factory-installed mechanical latch maintains the selected contact position after the operating signal has been removed. This makes the contactor suitable for applications where maintained switching, reduced coil power consumption or stable contact positioning is required.
Typical Applications
- Industrial motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Production and processing machinery.
- Maintained-load switching circuits.
- OEM machinery and automation panels.
