The Eaton C25GNF390B is a heavy-duty, 3-pole definite purpose contactor designed for high-demand HVACR and industrial motor control applications. Engineered for 90A inductive and 120A resistive loads, this G-Frame component is a direct technical equivalent to the 42GE35AG and 42GE35AG106 models. It features a versatile 208-240V AC coil (50/60 Hz), making it an ideal choice for commercial air conditioning systems, large refrigeration racks, and resistance heating setups. The open-style construction includes robust box lug terminals alongside standard 1/4 inch quick connect terminals for streamlined field wiring. With a maximum voltage rating of 600VAC, this non-reversing contactor handles high-inrush currents common in three-phase compressor starts while maintaining superior arc suppression. Designed for surface mounting, its compact footprint allows for efficient integration into existing control panels, ensuring reliable electrical switching for critical heating and cooling infrastructure. Key Benefits Universal Compatibility: Direct physical and electrical cross-reference for the 42GE35AG and 42GE35AG106 series. High Current Rating: Rated for 90 Amps inductive load, providing the capacity needed for large industrial motors and HVAC compressors. Flexible Terminal Design: Equipped with large box lugs for high-gauge wire and dual quick connects for control circuit speed. Industrial Durability: Double-break contacts and a high-quality 240V magnetic coil ensure consistent performance in high-cycle environments. Broad Application: Suitable for HVACR, resistance heating, and general-purpose motor starting up to 600V. Common Questions Is the 208-240VAC coil compatible with a 24V control circuit? No, the Eaton C25GNF390B requires a high-voltage control signal. If your thermostat or controller outputs 24VAC, you will need a transformer or a different contactor model with a 2VAC coil. Can this contactor replace a 2-pole model in a 3-phase system? For 3-phase equipment, a 3-pole contactor like this one is required to break all three lines of power simultaneously. It cannot be substituted by a 2-pole unit if the system demands a full 3-pole disconnect. What is the difference between the 90A inductive and 120A resistive ratings? The 90A rating applies to inductive loads like motors and compressors which have high startup inrush. The 120A rating is for resistive loads, such as electric heating elements, where the current remains constant upon startup.
