White-Rodgers 94-389 Contactor

The White-Rodgers 94-389 is a professional-grade 1-pole definite purpose contactor designed for high-cycle reliability in residential central air conditioning and light commercial refrigeration systems. Engineered with a 120V AC coil (50/60 Hz), this unit features a 30-amp contact rating, making it a robust solution for controlling compressors and fan motor loads. This model serves as the direct replacement for the C301NU20 and is built to NEMA standards with a compact 3 1/4" x 2" x 2 1/2" footprint to fit tight electrical enclosures.

For technicians simplifying field repairs, the 94-389 utilizes straight-through wiring and a universal mounting bracket that aligns with existing OEM hole patterns. The coil is spec'd at 420 Ohms DC resistance with a low 42 mA draw, providing efficient 5 VA nominal performance while managing up to 20 VA inrush. With a temperature range of -40°F to 150°F and 1/4" quick connect terminals plus screw terminals, it ensures a secure electrical connection and long-term durability in demanding HVAC environments.

• OEM Compatibility: Serves as a universal HVAC contactor replacement for common Type 117 devices and specific 1.5 pole configurations.
• Contractor-Friendly Install: Features straight-through wiring and a universal bracket to reduce labor time during AC contactor replacement.
• Precision Engineering: Heavy-duty 30A inductive load rating ensures stable switching for high-draw compressors and inductive motor loads.
• High-Cycle Life: Built to meet ARI specifications, facilitating over 200,000 mechanical cycles for consistent system uptime.

Can I use this 1-pole contactor to replace a 2-pole model?
No. A 1-pole contactor only interrupts one "hot" leg of the circuit. If your system requires both legs to be disconnected for safety or code compliance, stay with a 2-pole unit.

What is the difference between FLA and LRA on this part?
The 30A rating refers to Full Load Amps (FLA), the continuous current the contacts can handle. Locked Rotor Amps (LRA) is the much higher momentary current the contactor withstands during motor startup.

Why does my contactor have a copper bar on one side?
This is a "shunt" or bus bar commonly found in 1.5 pole contactors. It maintains a continuous path for one side of the line while the switching pole interrupts the other.
