Eaton AH430R9W Locking Receptacle 30A 250V 3-pole

Product Description

The EATON AH430R9W is a 3-pole locking receptacle rated for 30 amps at 250 volts. Locking receptacles are designed to accept a twist-lock plug that physically locks into place to prevent accidental disconnection under load or vibration. This type of device is installed at the outlet point of a branch circuit where secure, positive electrical connection is required. Licensed electricians install this receptacle as part of fixed wiring in commercial, industrial, and heavy-duty residential applications. The 30A, 250V rating makes it suitable for motor loads, generators, portable equipment connections, and similar high-draw circuits.

This receptacle is used in applications where standard straight-blade outlets are not sufficient due to vibration, repeated connection cycles, or code requirements for positive-locking connections. Typical installations include generator hookups, compressor circuits, welding equipment outlets, and commercial service panels. It is appropriate for both new construction wiring and service replacement work on existing branch circuits requiring a 3-pole, 30-amp, 250-volt locking configuration.

Key Features

• 3-pole locking configuration for secure, vibration-resistant connections
• Rated 30 amps at 250 volts for heavy-duty branch circuit use
• Twist-lock design prevents accidental plug disconnection under load
• Suitable for generator, compressor, and motor circuit outlet installations

Compatibility

Designed as an OEM-style replacement or new-installation locking receptacle for 3-pole, 30-amp, 250-volt branch circuits requiring a twist-lock outlet device.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker and verify absence of voltage with a meter before beginning wiring. Ensure the branch circuit conductor sizing, overcurrent protection, and enclosure type match the 30A, 250V rating of this device. Do not exceed the device amperage or voltage ratings under any operating condition.
