White-Rodgers 90-246 Contactor

The White-Rodgers 90-246 is a 2-pole definite purpose contactor engineered for heavy-duty HVACR applications. Operating on a 208/240V coil, this 30-amp contactor provides reliable switching for compressors and motors. It is the direct replacement for the 94-390, ensuring zero-latency installation for technicians servicing residential and commercial cooling systems. Built with double-break contacts for positive make-and-break cycles, it eliminates erratic switching and premature pitting.

For high-cycle environments, the mechanical contactor utilizes Type 122 construction with a low-VA coil to reduce heat generation and extend service life. The universal mounting bracket is pre-drilled to match field-standard footprints, while screw terminals and dual 1/4-inch quick connects allow for flexible wiring across various OEM replacement scenarios. With 40A resistive and 30A inductive ratings, this component handles high-current loads safely within the White-Rodgers 90 series ecosystem.

• Universal Compatibility: Replaces the old 94-390 and fits standard 2-pole footprints for fast field repairs.
• Enhanced Durability: Double-break contacts ensure long-term reliability under inductive loads.
• Efficient Coil: Low-power 208/240V coil stays cool to prevent insulation breakdown.
• Technician-Ready: Features diverse termination options including pressure connectors and quick-connect spades.

Common Questions & Troubleshooting

Q: Can I replace a single-pole contactor with this 2-pole model?
A: Yes, though you must ensure the coil voltage matches and that you account for the second pole’s break in the circuit, which provides an additional safety measure by disconnecting both legs of the power supply.

Q: What should I check if the contactor chattered or hums?
A: Check for proper voltage at the coil terminals (208/240V). Lower voltage can cause the plunger to struggle, while debris or insects in the contact areas can prevent a complete seal.

Q: Is this suitable for 40-amp resistive loads?
A: Yes, while rated for 30A inductive (compressors), this unit is typically rated for up to 40A resistive loads, such as electric heat strips.
