White-Rodgers 94-394 Contactor
Field technicians looking for a rugged, universal replacement for residential AC units should spec the White-Rodgers 94-394 contactor. This single-pole definite purpose contactor is engineered for continuous duty, featuring a 40 amp contact rating and a 24 VAC coil compatible with both 50 and 60 Hz systems. Designed with straight-through wiring, it serves as a direct upgrade for many OEM 1-1/2 pole devices and Type 117 configurations. The universal mounting bracket aligns with existing hole patterns, while the combination of screw terminals and double 1/4" quick-connects streamlines field installation. With a coil resistance of 16.5 Ohms and a maximum inrush of 20 VA, this unit provides reliable switching for compressor and fan motor loads in demanding environments, operating effectively across a temperature range of -40°F to 150°F.
Key Benefits- Universal Compatibility: Replaces a wide range of OEM Type 117 and 1-1/2 pole contactors in residential HVAC systems.
- High Amperage Capacity: Rated for 40 amps, providing ample headroom for most residential condensing units.
- Flexible Termination: Equipped with both screw terminals and 1/4" quick-connects for versatile wiring options.
- Standardized Footprint: The 3-1/4" x 2" x 2-1/2" dimensions and universal plate ensure it fits standard control boxes without modification.
- Durable Construction: Built for continuous duty with a dust-resistant cover to maintain contact integrity over time.
Can I use the White-Rodgers 94-394 to replace a 30 amp contactor?
Yes, you can safely use a 40 amp contactor to replace a 30 amp unit, as the higher amperage rating allows the contacts to handle the load with less heat and wear. Ensure the 24V coil voltage matches your system's control circuit.
What does '1.5 pole' vs '1 pole' mean for this part?
The 94-394 is a 1-pole device often referred to as 1.5 pole because it includes a shunt or bus bar on the second leg. This allows one leg of the power to remain "hot" while the contactor breaks the circuit on the primary pole.
Is this contactor suitable for heat pump applications?
Absolutely. Its 50/60 Hz frequency rating and 40A capacity make it ideal for residential heat pump condensers and straight-cool air conditioning systems.
