White-Rodgers 94-388 Contactor

The White-Rodgers 94-388 is a high-duty single pole definite purpose contactor designed specifically for residential central air conditioning and light commercial HVACR applications. Engineered for field reliability, this 24V HVAC contactor features a 30-amp inductive rating and is built to withstand the rigorous cycling demands of modern condensing units. This model is a direct White-Rodgers replacement for various OEM Type 117 devices, ensuring a seamless fit during service calls. It utilizes straight-through wiring and a universal mounting bracket, which drastically simplifies the installation process in tight electrical cabinets. The coil is rated for 50/60 Hz operation with a DC resistance of 16.5 Ohms, providing efficient switching performance throughout a temperature range of -40°F to 150°F. For contractors looking for a 30A condenser contactor that combines durability with easy installation HVAC parts, the 94-388 delivers consistent arc suppression and mechanical longevity without the need for additional modifications.

• Universal Compatibility: Includes a universal-style mounting bracket that matches existing hole patterns for fast OEM replacement.
• Versatile Termination: Features both screw terminals and 1/4-inch quick-connect terminals to accommodate various field wiring configurations.
• Enhanced Durability: Specifically designed as a 1.5 pole device with a shunt (bus bar), increasing reliability over standard single-pole alternatives.
• Optimized Performance: Silver cadmium oxide contacts provide superior resistance to welding and pitting in high-cycle cooling environments.

What does it mean that this is a 1.5 pole contactor?
The 94-388 features one set of switching contacts for the "hot" leg and a permanent bus bar (shunt) for the neutral or second leg. This allows for constant power to the crankcase heater while switching the compressor and fan loads.

Is the coil compatible with 50Hz and 60Hz systems?
Yes, the 24V coil is rated for both 50Hz and 60Hz frequencies, making it suitable for standard North American residential applications and various international equipment configurations.

Can I use this to replace a 25-amp contactor?
In most cases, yes. Upgrading to a 30-amp contactor from a 25-amp unit provides a higher safety margin and can extend the service life of the component, provided the physical footprint and coil voltage match.
