Eaton C25FNF360T (42EF35AJ) Contactor

The Eaton C25FNF360T (which serves as a direct technical replacement for the 42EF35AJ) is a heavy-duty, 3-pole definite purpose contactor engineered for demanding HVACR systems. Built on a standard F-frame, this 60A contactor is rated for 60 amps inductive full-load and 75 amps resistive, making it a reliable choice for high-capacity motor and compressor switching. It operates with a standard 24V AC coil (50/60 Hz), ensuring seamless integration into existing low-voltage control circuits found in commercial refrigeration and rooftop units. The open enclosure design features a rugged metal mounting plate and versatile box lugs and quick-connect terminals, providing the terminal flexibility needed for quick field wiring. As a non-reversing Eaton C25 series component, it is meticulously designed to reduce arcing and manage the high inrush currents of large motor starts without premature failure. This unit meets all major industrial standards, including UL and CSA, for high-cycle duty in professional climate control infrastructure.

• Broad Compatibility: A proven cross-reference for the 42EF35AJ contactor and several Siemens/Furnas Class 42 models, saving you time during unit retrofits.
• High Amperage Rating: Rated for a 60-amp full-load current and up to a 360-amp locked rotor at 230V, providing the thermal overhead required for large HVAC compressors.
• Dual Terminal Connectivity: Equipped with side-by-side box lugs and quick connects to accommodate various wire gauges and termination types in the field.
• Encapsulated Coil: Designed to prevent dust and contaminant ingress, ensuring consistent magnet operation and reducing audible chatter or hum.
• Flexible Mounting: The universal metal baseplate simplifies installation in vertical, horizontal, or tabletop orientations within the control panel.

Is the Eaton C25FNF360T a direct replacement for the 42EF35AJ?
Yes, the Eaton C25FNF360T is electrically and mechanically equivalent to the 42EF35AJ. Both are 3-pole, 60A inductive contactors with 24VAC coils and share the same mounting footprint, making them interchangeable for HVAC service calls.

What wire size is compatible with the box lugs?
The positive setscrew box lugs on this 60A unit are typically designed to accept wire sizes ranging from 14 AWG to 2 AWG, depending on the specific lug configuration, though most contractors utilize them for 4 or 6 AWG in high-amperage HVAC applications.

Can auxiliary contacts be added to this model?
Yes, the C25 series F-frame allows for the field installation of side-mounted auxiliary contacts (1NO, 1NC, or 2NO) if your control logic requires status feedback or interlock capabilities.
