Eaton C400GK42A Contactor

Product Description

The EATON C400GK42A is a contactor designed for switching and controlling electrical loads in industrial and commercial power distribution systems. Contactors in this class are used to make and break high-current circuits under load, providing reliable on/off control for motors, HVAC equipment, compressors, and other high-draw electrical devices. Licensed electricians and industrial maintenance technicians are the primary installers. The C400GK42A fits into panel and enclosure-based control schemes where durable, repeatable switching performance is required.

This contactor is suited for commercial and industrial applications where automated or manual control of high-current loads is needed. Typical install scenarios include motor control centers, HVAC rooftop unit panels, compressor control panels, and industrial machinery enclosures. It is appropriate for both new installations and direct replacements of worn or failed contactor units in existing control systems.

Key Features

• Heavy-duty contactor construction built for repeated make-and-break switching cycles
• Designed for integration into motor control and power distribution panel assemblies
• Suitable for commercial HVAC, compressor, and industrial motor load applications
• OEM-style form factor supports direct replacement in existing control enclosures

Compatibility

Designed as an OEM-style replacement contactor for commercial and industrial motor control and power distribution applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit at the panel before removing the existing contactor or making any wiring connections. Verify that coil voltage and load ratings match the application requirements before installation. Do not energize the contactor with the enclosure open or with any terminals exposed.
