Copeland 512--07 Industrial Compressor Contactor

The Copeland 512--07 Industrial Compressor Contactor is a purpose-built switch that controls the electrical power to a compressor motor in industrial refrigeration and HVAC equipment. The 512--07 model designation identifies this specific Copeland contactor, intended for installation in control panels and starter assemblies where reliable motor control is required. When a control circuit energizes its coil, the main contacts close to feed the compressor; when the coil is de-energized, the contacts open to stop the motor, providing a straightforward method to start and stop large-capacity compressors as part of a coordinated cooling system. The contactor serves as the interface between low‑voltage control signals and high‑current motor loads, isolating control circuits from motor surges while enabling safe engagement of the compressor. This Copeland component is designed to withstand the demands of industrial environments and to integrate with standard electrical control setups used in commercial and industrial refrigeration applications, forming a key part of starter assemblies and protection schemes in cooling systems.
