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 11B1150024 provides three normally open poles for switching three-phase motors and other industrial AC loads.
Its 24 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.
