Key Features
High-Performance Switching
The Schneider BMEH584040S handles motor starting currents up to 10×In (400A) for 100ms, protecting against voltage dips during compressor or pump startups. Its arc chute design reduces contact welding risks even in dusty environments.
Versatile Control Options
Universal coil compatibility (24–240V AC/DC) eliminates the need for separate DC/AC models. Integrated mechanical indicators provide visual status confirmation for troubleshooting.
EcoStruxure Integration
When paired with Schneider TESYSULT communication modules, enables real-time current monitoring and predictive maintenance alerts via Modbus TCP or Ethernet/IP protocols.
Applications
- Industrial Motor Control: DOL/Star-Delta starters for 7.5–30kW three-phase motors.
- HVAC Systems: Compressor control in chillers with frequent start/stop cycles.
- Renewable Energy: Solar inverter DC switching and wind turbine pitch control.
- Material Handling: Conveyor belt motor switching in mining/automotive plants.
- Water Treatment: Pump control panels with surge-protected coil circuits.
The contactor’s IP20 protection and vibration resistance (5–150Hz) make it suitable for marine engine rooms and mobile equipment.
