TOGAMI PAK-400H(J) is a high-capacity open-type magnetic contactor from the PAK-H series (often listed as PAK-400H or PAK-400H(J) in catalogs), designed for heavy industrial applications like large motor control, heavy machinery, and high-power resistive/inductive load switching.
Key Features
- High AC-3 rating for motor control: 400A rated current, up to 200kW at 440V
- Twin movable contact structure for reliable low-current DC switching (supports DC24V at 10mA).
- Built-in 2NO + 2NC (or up to 3NO+3NC in some configs) auxiliary contacts for signaling, interlocking, and control circuits.
- Cassette-style screwless coil for quick, tool-free replacement and minimal downtime.
- One-touch DIN rail mounting (35mm IEC/DIN standard) with visible coil ratings post-installation (though for this high-capacity size, panel/screw mounting is primary; DIN rail clip may be optional or via adapter in some setups).
- Removable cover for easy contact inspection/maintenance; compliant with JEM standards for industrial reliability.
