Eaton AH420C7W Twist-lock Connector 3P4W 20A 480V

Product Description

The EATON AH420C7W is a heavy-duty twist-lock electrical connector rated for three-phase, four-wire (3P4W) circuits at 20 amps and 480 volts. Twist-lock connectors mechanically secure the connection between a plug and receptacle by rotating to lock, preventing accidental disconnection under load. This connector is designed for industrial and commercial electrical distribution systems where a reliable, code-compliant wiring device is required. Licensed electricians and experienced electrical contractors are the primary installers of this type of device.

The AH420C7W is suited for industrial facilities, commercial construction, and heavy-duty service applications where 480-volt three-phase power distribution is standard. Typical installations include temporary power distribution panels, generator connections, and equipment drops requiring a secure, locking wiring device. The 3P4W configuration supports grounded three-phase circuits commonly found in motor loads, HVAC equipment, and process machinery.

Key Features

• Twist-lock design prevents accidental disconnection under load
• Rated 20 amps at 480 volts for heavy-duty service
• 3P4W (three-pole, four-wire) configuration for grounded three-phase circuits
• Designed for industrial and commercial power distribution applications

Compatibility

Designed as an OEM-style replacement or direct-fit connector for industrial and commercial three-phase, four-wire 480-volt twist-lock wiring device applications.

Installation Notes

Installation must 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 beginning any wiring work. Verify that the supply circuit voltage, amperage, and wire configuration match the connector ratings before making connections. Do not exceed the 20-amp or 480-volt ratings of this device.
