    Application

    The Noark Ex9CK75B30G7 is a 75A, 3-Pole (3NO) Definite Purpose Contactor with a 120V 50/60Hz coil, designed for demanding switching applications such as HVAC equipment, compressors, pumps, lighting, and electric heating systems. Its definite purpose rating makes it well suited for high-cycle loads where a standard general-purpose contactor would be undersized.

    • Ideal for commercial and industrial HVAC, refrigeration compressors, and motor-load switching up to 75A
    • 3NO contact configuration supports standard 3-phase load control; coil operates on common 120V control circuits
    • Part of the Noark Ex9CK series — consult the Noark product datasheet for full electrical and mechanical ratings

    Not sure if this contactor fits your panel or control circuit? Send us your system details and we'll confirm the right fit.

    The Ex9CK75B30G7 is a Definite Purpose Contactor, meaning it is specifically rated for high-cycle applications such as HVAC compressors, refrigeration equipment, pumps, and electric heating loads — not just general-purpose motor switching. Always verify the full load amp (FLA) and locked rotor amp (LRA) ratings against your equipment specs using the Noark datasheet.

    The Ex9CK75B30G7 may serve as a cross-replacement for other 75A 3-pole definite purpose contactors (e.g., from Honeywell, Schneider, or Siemens) provided the coil voltage (120V 50/60Hz), contact configuration (3NO), frame dimensions, and electrical ratings align. Always compare full specs before substituting, and contact our team — we can help confirm cross-reference compatibility.

    The coil voltage on the Ex9CK75B30G7 is factory-set at 120V 50/60Hz and is not typically field-changeable on definite purpose contactors. However, the Noark Ex9CK series is available in other coil voltages (e.g., 24V, 208–240V). If you need a different control voltage, contact us and we can source the correct Ex9CK variant for your application.
