Copeland Comfort Control (White Rodgers) 90-163 Contactor

The White Rodgers 90-163 is a heavy-duty, 3-pole definite purpose contactor designed for high-performance switching in central air conditioning and commercial refrigeration systems. Rated for 30 amp inductive loads and up to 600 VAC, this electromechanical component features a 24V coil with a low wattage design (4.5 VA nominal) to reduce power consumption and heat generation during continuous duty. Engineered with silver alloy double break contacts, the 90-163 ensures a positive make and break, preventing terminal pitting and extending the service life of HVAC compressor and fan motor circuits.

For the service technician, the 90-163 simplifies field replacements with an interchangeable mounting plate and a compact footprint that fits standard control panels. The unit supports any position mounting and provides flexible termination options including pressure connectors and double 1/4-inch quick-connect terminals. Whether you are servicing a three-phase motor or a resistive heating element, this 3PNO contactor (3-Pole Normally Open) meets UL and CSA standards for industrial and residential applications, operating reliably in temperatures ranging from -40°F to 150°F.

• High Current Capacity: Rated for 30A inductive and 40A resistive loads, providing robust switching for 3-phase HVAC systems.
• Universal Mounting: Features an interchangeable mounting plate for easy installation in various condensing unit configurations.
• Efficient Coil Performance: The 24V AC coil draws only 187 mA, minimizing the load on the system's control transformer.
• Proven Durability: Equipped with double break silver alloy contacts to ensure reliable electrical continuity and prevent welding.

• Can I use this to replace a single-pole contactor? No, this is a 3-pole contactor designed specifically for three-phase equipment or systems requiring simultaneous switching of three legs of power.
• How do I test if the coil is bad? Use a multimeter to check for 24V at the coil terminals. If voltage is present but the plunger doesn't pull in, or if the DC resistance is significantly different from 7.2 ohms, the coil has likely failed.
• What does the 30 amp rating signify? This represents the maximum full load amps (FLA) the contactor can safely switch. Always ensure your equipment's FLA does not exceed this rating.
