Leviton Telcom W3125-B11 Locking Inlet 3P4W 125A

Product Description

The LEVITON TELCOM W3125-B11 is a round pin locking inlet rated for 3-phase, 4-wire electrical connections at 125 amps. This inlet provides a secure, twist-lock interface for high-amperage power distribution in industrial and commercial electrical systems. The locking pin design prevents accidental disconnection under load conditions, making it suited for demanding service environments. Licensed electricians install this inlet as part of panel feed assemblies, generator connections, or power distribution equipment where reliable 3-phase power transfer is required.

This inlet is intended for commercial and industrial applications where 3-phase power distribution is standard. It is commonly installed in power distribution panels, generator hookups, and temporary power assemblies on construction sites or in industrial facilities. The 125-amp rating supports heavy electrical loads typical of 3-phase service equipment. This is a single-unit hardware accessory handled by licensed electrical contractors operating under NEC guidelines.

Key Features

• Round pin locking design for secure, twist-lock power connection
• 3-phase, 4-wire configuration for industrial and commercial power distribution
• 125-amp current rating supports heavy-load service equipment
• Single-unit (sold individually) hardware accessory

Compatibility

Designed as an OEM-style inlet for 3-phase, 4-wire power distribution assemblies requiring a round pin locking interface rated at 125 amps.

Installation Notes

Installation must be performed by a licensed electrician in accordance with applicable NEC requirements for high-amperage 3-phase wiring. De-energize and lock out the circuit at the panel before beginning any installation or service work. Verify that the inlet rating matches the connected load and overcurrent protection before energizing. Do not exceed the 125-amp current rating of the device.
