Legrand cs8164c Locking Connector 50A 480V 3P4W

Product Description

The LEGRAND cs8164c is a straight-body locking connector rated for 50 amps at 480 volts in a 3-phase, 4-wire configuration. Built for industrial and heavy commercial electrical distribution, it provides a secure, twist-lock termination point where a mating plug or cord set connects to a fixed wiring system. CSA and UL approvals confirm it meets the safety standards required for commercial and industrial installations. Electricians specify this connector for high-current branch circuits and equipment connections where accidental disconnection under load is a concern.

This connector suits heavy commercial and industrial applications where 3-phase, 480-volt power is distributed to machinery, HVAC equipment, temporary power setups, or large motor loads. The straight-body design accommodates standard cord-end wiring. The non-NEMA locking configuration is common in industrial facilities, manufacturing environments, and equipment rooms where high-amperage, multi-phase circuits are standard.

Key Features

• 50-amp, 480-volt rating for high-current 3-phase circuits
• 3-pole, 4-wire configuration supports balanced 3-phase loads with a neutral
• Straight-body connector design for standard cord-end terminations
• Non-NEMA locking interface resists accidental disconnection under load
• CSA and UL listed for commercial and industrial use
• Black and white color body for visual identification

Compatibility

Designed as an OEM-style replacement or new-installation locking connector for 50-amp, 480-volt, 3-phase, 4-wire electrical systems using a non-NEMA locking configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before making any wiring connections. Verify conductor sizing is appropriate for the 50-amp rating and that the circuit overcurrent protection matches the application requirements. Do not exceed the voltage or amperage ratings marked on the connector body.
