Description
Heavy-duty industrial motor control operations require reliable switching components, and the Mitsubishi Electric SD-N300 DC24V delivers high-performance circuit control in demanding B2B environments. This DC-operated magnetic contactor is engineered for non-reversing, Direct On Line (DOL) motor starting and electrical load switching applications. Equipped with a low-consumption 24 VDC control coil, this contactor integrates cleanly into automated control loops, interfacing directly with PLC and DCS systems without the need for interposing high-power relays.
Features
- Standard non-reversing configuration for Direct On Line (DOL) starting.
- DC-operated coil structure designed to minimize power consumption and heat generation.
- High-durability power contacts rated for heavy-duty industrial switching cycles.
- Robust housing design suitable for standard surface mounting configurations.
Applications
- Direct On Line (DOL) motor starting and control systems.
- Heavy industrial processing, manufacturing, and assembly plants.
- Water treatment facilities, pump stations, and ventilation systems.
- Power distribution systems and auxiliary contactor control circuits.

Installation Guidelines
Ensure that all upstream power is locked out and tagged out prior to installation. This contactor is designed for surface mounting inside a sealed, dust-free industrial enclosure. Maintain standard electrical clearances around the arc chute and ventilation pathways to ensure proper heat dissipation. Connect control and main power cables using correctly sized ring terminals or wire lugs, adhering strictly to the torque requirements specified for the terminal fasteners.
