Leviton Telcom 430MF12WLEV 30 Amp Mechanical Interlock

Product Description

The LEVITON TELCOM 430MF12WLEV is a 30-amp mechanical interlock device used in electrical distribution and switching applications. A mechanical interlock prevents two circuit positions from being engaged simultaneously, providing a physical safety barrier against backfeed, cross-connection, or inadvertent energization of a circuit. This type of hardware accessory is commonly installed by licensed electricians during panel work, transfer switch installations, and generator hookup configurations where dual-throw or lockout protection is required.

The 430MF12WLEV is suited for residential and light commercial electrical applications where a hard-mechanical interlock solution is needed. It is sold as a single unit and falls within the hardware accessories category, making it applicable to breaker interlock and switching safety scenarios. Installers working on standby power, generator transfer arrangements, or dual-feed panel configurations will find this type of interlock a practical compliance and safety component.

Key Features

• 30-amp mechanical interlock rating for reliable circuit isolation
• Physical interlock mechanism prevents simultaneous engagement of two circuit positions
• Single-unit packaging suitable for individual installation projects
• Hardware accessory category component for electrical panel and switching applications

Compatibility

Designed as an OEM-style replacement or upgrade mechanical interlock for 30-amp electrical switching and panel interlock applications. Verify fitment against your specific panel or breaker model before installation.

Installation Notes

Installation should be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or circuit before beginning any installation work. Confirm that the interlock fits the target breaker or panel slot securely before final fastening. Do not force the interlock into position if alignment does not match the intended breaker or enclosure configuration.
