Leviton Telcom 3330 Locking Single Receptacle 3P3W

Product Description

The LEVITON TELCOM 3330 is a locking single receptacle configured in a 3-pole, 3-wire arrangement without a NEMA designation. Locking receptacles are used in commercial, industrial, and trade applications where a secure, twist-lock connection is required to prevent accidental disconnection under load or vibration. Electricians and electrical contractors install this type of device in panel boards, equipment drops, and service outlets where a positive mechanical lock between plug and receptacle is critical to safe, continuous operation.

This receptacle is suited for applications where a 3-pole, 3-wire non-NEMA locking configuration is specified. Typical install scenarios include industrial equipment hookups, portable generator connections, and commercial electrical service outlets where standard straight-blade receptacles are not appropriate. The non-NEMA designation indicates a specialized or proprietary locking configuration; verify the mating plug configuration before ordering to ensure proper fit.

Key Features

• Locking twist-lock design prevents accidental plug withdrawal under load or vibration
• 3-pole, 3-wire configuration for dedicated circuit applications
• Non-NEMA designation suits specialized or proprietary wiring device applications
• Single receptacle format for straightforward panel or wall-box installation
• Sold individually (unit of measure: each)

Compatibility

Designed as an OEM-style locking receptacle for 3-pole, 3-wire non-NEMA applications; confirm mating plug part number and configuration prior to installation, as no specific compatible models or systems were identified in the available product data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the breaker and verify zero voltage with a meter before handling any wiring connections. Confirm box fill calculations and mounting depth are adequate for the selected enclosure before securing the device. Do not exceed the rated current and voltage for the receptacle as specified on the device marking.
