11B1150048 – 3P CONTACTOR B115.00 48V
Lovato 11B1150048 is a B115 three-pole power contactor with a 110 A AC-3 rating, 61 kW motor capacity at 400 V and a 48 V AC/DC control coil for industrial motor switching.
Why Choose the Lovato 11B1150048 Three-Pole Contactor?
The Lovato 11B1150048 is a heavy-duty three-pole power contactor designed for controlling industrial motors and high-current electrical loads. As part of the Lovato B Series, this B115 contactor provides dependable electromagnetic switching for machinery, automation systems and electrical distribution equipment.
Its three normally open main poles provide an AC-3 operational current rating of 110 A at voltages up to 440 V. The contactor also supports three-phase motors rated up to 61 kW at 400 V AC, making it suitable for demanding motor starting and switching applications.
The 11B1150048 features an AC/DC coil rated at 48 V, allowing it to operate from either 48 V AC or 48 V DC control circuits. Screw mounting, robust power terminals and a mechanical life of 10,000,000 operating cycles support reliable integration into industrial control panels.

Reliable Switching for High-Power Motors
Power contactors use an electromagnetic coil to open and close their main contacts, enabling high-current equipment to be controlled by a lower-power command circuit. The Lovato 11B1150048 provides three normally open poles for switching three-phase motors and other industrial AC loads.
Its 48 V AC/DC coil supports integration with low-voltage automation and control systems, while the high current and motor power ratings suit demanding machinery. Auxiliary contacts, overload protection and mechanical interlocking accessories can be selected separately to create a complete motor control assembly.
Typical Applications
- Three-phase industrial motor starters.
- Pumps, fans and compressor systems.
- Conveyors and material-handling equipment.
- Industrial heating and resistive loads.
- Production and processing machinery.
- Electrical control panels and automation systems.
