Contactor · 400A · 3P 3NO · 100-250V AC/DC coil with 2NO+2NC auxiliary contacts · Noark Electrical EX9C400F22K

What this product is for

The Noark Electrical EX9C400F22K is a high-current, full-voltage non-reversing IEC contactor for switching large three-phase loads. It is built for motor control and power switching applications that require 400A capacity, 3 normally open main contacts, and auxiliary contacts for interlocking, signalling, or status feedback.

Use for

Use for large pumps, compressors, chillers, process equipment, manufacturing lines, and control panels where a 400A contactor is required. The 100-250V AC/DC wide-range electronic coil is useful when panel designs vary by control voltage or when reducing stocked coil variants matters.

Avoid for

Avoid for reversing applications unless paired with the correct reversing arrangement and accessories. Avoid where conductor termination requirements, lug selection, or enclosure space have not been confirmed, as this frame size requires proper luging, mounting clearance, and coordination with the rest of the motor starter assembly.

Best for

Best for industrial electricians, panel builders, OEMs, and maintenance teams specifying a high-amp contactor with built-in auxiliary contacts and a broad control-voltage range. It is also a practical choice where CSA and UL recognition are required for Canadian and North American panels.

Installed in

Typically installed in industrial control panels, MCC sections, pump control panels, compressor panels, and machinery cabinets. Plate mounting is commonly used. Product dimensions are approximately 8.58 x 6.30 x 9.06 in (218 x 160 x 230 mm), so enclosure depth and wire-bending space should be checked before ordering.

Why this product exists

This contactor exists to switch high current loads reliably while simplifying control design with one wide-range coil for 100-250V AC/DC systems. The built-in 2NO+2NC auxiliary contacts help reduce added components for control logic, indication, and feedback.

Compared with similar products

Compared with lower-amp contactors, this 400A frame is intended for substantially larger motors and heavier duty switching. Compared with fixed-voltage coil models, the wide-range coil can reduce SKU count in service stock and panel builds. As typical guidance only, contactor selection should still be coordinated with motor full-load current, duty category, short-circuit protection, and local electrical code. Actual suitability depends on the application, enclosure, ambient conditions, and upstream protection.
