Definite Purpose Contactor · 40A 2-Pole 208-240V Coil · Open Type Eaton C25BNB240B
SKU: EAT-C25BNB240B
Eaton C25BNB240B is a 2-pole definite purpose contactor rated 40A with a 208-240V AC coil for panel-mounted switching of compressors, heating loads, motors, and similar equipment. Typical selection guidance: match pole count, coil voltage, and load rating to the control circuit and connected equipment; actual suitability depends on the application and local electrical code.
What this product is for
This definite purpose contactor is used to switch line-voltage loads from a control circuit in HVAC, heating, refrigeration, motor, and other equipment panels. It is a 2-pole, open-type contactor with a 40A rating and a 208-240V AC coil.
Use for
Use for compressors, electric heating loads, fan motors, condensers, and other equipment that requires a 2-pole contactor with a 208-240V AC control coil. It is commonly used where a compact panel-mounted contactor is needed.
Avoid for
Avoid for applications that require a different coil voltage, enclosed assembly, reversing function, or a higher load rating than the contactor is designed to handle. Do not substitute based on amperage alone without confirming coil voltage, pole configuration, and equipment requirements.
Best for
Best for service replacement and OEM-style control panels where electricians or HVAC technicians need a compact 2-pole definite purpose contactor with a 208-240V AC coil and 40A switching capacity.
Installed in
Typically installed in control panels, condensing units, air handlers, electric heat equipment, refrigeration systems, and other industrial or commercial equipment cabinets. Panel space and terminal layout should be checked before ordering.
Why this product exists
This product provides a straightforward way to switch medium-duty line-voltage loads from a separate control circuit. In trade use, the key buying checks are usually coil voltage, pole count, mounting style, and contact rating. Actual performance depends on load type, duty cycle, enclosure conditions, and local electrical code.
Compared with similar products
Compared with general-purpose contactors, a definite purpose contactor is typically selected for compact equipment applications such as HVAC and heating controls. Compared with versions that use 24V or 120V coils, this model is specifically for 208-240V AC coil circuits, so coil voltage must match the control circuit exactly.
