Copeland 912-0001-16 Auxiliary Contactor Switch 1NC A1 90 Amp

Product Description

The Copeland 912-0001-16 is an OEM auxiliary contactor switch rated at 90 amps, designed for use in refrigeration and HVAC systems where reliable electrical switching is critical. This component serves as an auxiliary contact block, providing a normally closed (1NC) contact configuration on the A1 position of the contactor assembly. Auxiliary contactors are essential control components in commercial refrigeration equipment, rooftop units, condensing units, and other HVAC systems. They work alongside the main contactor to provide status feedback, interlocking, and control circuit functions that keep equipment running safely and efficiently. The 1NC configuration means the contact is closed when the contactor coil is de-energized and opens when the coil is energized, a standard setup used in motor control centers, compressor panels, and refrigeration control circuits. HVAC technicians and refrigeration mechanics rely on this type of component to restore full control circuit functionality when a contactor auxiliary block fails or wears out. At 90 amps, this switch is built for heavy-duty commercial and industrial applications where high current loads are common, such as large compressor contactors found in commercial refrigeration racks and rooftop HVAC equipment. Using a genuine Copeland OEM replacement part ensures proper fit, reliable operation, and compatibility with the original equipment. This is a direct OEM replacement, which means no modifications or adapters are needed during installation. Technicians working on Copeland-brand refrigeration and HVAC systems can install this part with confidence, knowing it meets the original equipment specifications. Keeping an accurate auxiliary contact signal in the control circuit helps prevent nuisance faults and protects downstream equipment from damage caused by incorrect switching status.

• Normally closed (1NC) auxiliary contact configuration on the A1 position for standard contactor control circuit applications
