Eaton CS8165EX Locking Plug 50A 480V 3-phase 3P4W

Product Description

The EATON CS8165EX is a heavy-duty locking plug rated for 50 amps at 480 volts, designed for three-phase, 3-pole 4-wire (3P4W) applications. Constructed from high-impact nylon in black, this plug is built for industrial and commercial environments where secure, vibration-resistant connections are required. The locking blade design prevents accidental disconnection under load, making it appropriate for generator connections, temporary power distribution, and heavy equipment installations. Electricians and electrical contractors are the primary installers of this device.

The CS8165EX is suited for use in industrial facilities, construction sites, commercial buildings, and any setting that requires a reliable 480-volt three-phase power connection. Its 3P4W configuration accommodates three hot legs and a ground, making it compatible with wye-configured three-phase power systems commonly found in industrial power distribution panels and portable generator setups requiring balanced three-phase loads.

Key Features

• 50-amp, 480-volt three-phase locking plug for industrial and commercial use
• 3-pole 4-wire (3P4W) configuration for wye three-phase circuits
• High-impact nylon body provides durability and resistance to physical damage
• Locking blade design prevents accidental disconnection
• Compact form factor suitable for tight panel and equipment installations

Compatibility

Designed as an OEM-style locking plug for industrial and commercial 480-volt three-phase power distribution applications requiring a 3P4W configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify absence of voltage with a meter before making any wiring connections. Use wire connectors and conductors rated for the full 50-amp load. Ensure the locking mechanism fully engages before energizing the circuit.
