Copeland 912-0001-20 Auxiliary Contact Switch 1NC 120V Contactor

Product Description

The Copeland 912-0001-20 is an auxiliary contact switch designed for use with contactors in HVAC and refrigeration electrical control systems. This single normally closed contact switch operates at 120 volts and is built to integrate directly with compatible contactor assemblies used in commercial and residential HVAC equipment. Auxiliary contact switches like the 912-0001-20 play a critical role in control circuit logic, providing feedback signals to control boards, safety circuits, and building automation systems. When the main contactor coil energizes or de-energizes, the auxiliary contact changes state, allowing the control system to monitor the status of compressors, condenser fans, and other motor loads. HVAC technicians and electrical contractors rely on auxiliary contacts to support interlocking, sequencing, and fault detection in multi-stage systems. The 1NC configuration means the contact is closed under normal conditions and opens when the contactor is energized, which is commonly required in safety shutdown circuits and alarm systems. The Copeland 912-0001-20 is sold as a single unit and is suited for replacement or new installation work on compatible Copeland contactor assemblies. Proper auxiliary contact selection is essential to system reliability, and using an OEM part like this one ensures compatibility with the original equipment design. HVAC service technicians, refrigeration mechanics, and commercial electricians working on split systems, rooftop units, chillers, and refrigeration racks will find this component useful for maintaining safe and efficient operation of contactor-based motor control circuits. This part is ideal for field service repairs, panel upgrades, and preventive maintenance programs.

• Auxiliary contact switch with 1 normally closed contact for contactor integration
• Rated for 120 volt control circuit applications in HVAC and refrigeration systems
• OEM Copeland part for reliable drop-in replacement on compatible contactor assemblies

Product Highlights

The Copeland 912-0001-20 auxiliary contact switch provides a 1NC contact configuration at 120 volts, making it a dependable replacement for contactor-mounted control circuit switching in commercial and residential HVAC systems.
