Reliable Heavy-Duty Motor Switching
Industrial contactors provide safe and efficient switching of high-current electrical circuits by allowing a low-power control signal to operate high-power motor circuits. This enables motors to be controlled by PLCs, push buttons, safety relays and automated control systems while keeping the control circuit electrically isolated from the power circuit.
The LOVATO B310 series is designed for demanding industrial environments where long operating life, dependable switching and high current capacity are required. Its robust design makes it ideal for continuous-duty applications in manufacturing, processing and heavy industrial automation.
Typical Applications
- Large three-phase motor starters.
- Industrial pumps and compressors.
- Material handling and conveyor systems.
- Process manufacturing equipment.
- Motor control centres (MCCs).
- Industrial switchboards.
- OEM machinery.
- Factory automation systems.
