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 11B11500110 provides three normally open poles for switching three-phase motors and other industrial AC loads.
Its AC/DC coil supports integration with different control supply arrangements, 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.
